How computers learn to recognize objects instantly | Joseph Redmon
Ten years ago, researchers thought that getting a computer to tell the difference between a cat and a dog would be almost impossible. Today, computer vision systems do it with greater than 99 percent accuracy. How? Joseph Redmon works on the YOLO (You Only Look Once) system, an open-source method of object detection that can identify objects in images and video -- from zebras to stop signs -- with lightning-quick speed. In a remarkable live demo, Redmon shows off this important step forward for applications like self-driving cars, robotics and even cancer detection.

Image Recognition and Python Part 1
Sample code for this series: http://pythonprogramming.net/image-recognition-python/ There are many applications for image recognition. One of the largest that people are most familiar with would be facial recognition, which is the art of matching faces in pictures to identities. Image recognition goes much further, however. It can allow computers to translate written text on paper into digital text, it can help the field of machine vision, where robots and other devices can recognize people and objects. Here, our goal is to begin to use machine learning, in the form of pattern recognition, to teach our program what text looks like. In this case, we'll use numbers, but this could translate to all letters of the alphabet, words, faces, really anything at all. The more complex the image, the more complex the code will need to become. When it comes to letters and characters, it is relatively simplistic, however. How is it done? Just like any problem, especially in programming, we need to just break it down into steps, and the problem will become easily solved. Let's break it down! First, we know we want to show the program an image, and have it compare it to patterns that it knows to make an educated guess on what the current image is. This means we're going to need some "memory" of sorts, filled with examples. In the case of this tutorial, we'd like to do image recognition for the numbers zero through nine. So we'd like to be able to show it any random 2, and have it know the image to be a 2 based on the previous examples of 2's that it has seen and memorized. Next, we need to consider how we'll do this. A computer doesn't read text like we read text. We naturally put things together into a pattern, but a machine just reads the data. In the case of a picture, it reads in the image data, and displays, pixel by pixel, what it is told to display. Past that, a machine makes no attempt to decide whether it is showing a couch or a bird. So, our database of what examples are will actually be pixel information. To keep things simple, we should probably "threshold" the images. This means we store everything as black or white. In RGB code, that's a 255, 255, 255, or 0, 0, 0. That is per pixel. Sometimes there is alpha too! What we can then do is take any image, and, if the pixel coloring is say greater than 125, we could say, this is more of a "white" and convert it to 255 (the entire pixel). If it is less than 125 or equal to it, we could say this is more of a "black" and convert it to black. This might be problematic in some circumstances where we have a dark color on a darker color, usually a type of image meant to fool machines. We could have something in place instead to find the "middle" color on average for the current image, and threshold anything lighter to white and anything darker to black. This works very well for two-dimensional images of things like characters, but less well for things with shading that are meant to accompany the image, say of something like a ball. Once we've done this, all we need to do is save the string of pixel definitions for a bunch of "example" texts. We can start with a bunch of fonts, plus some hand drawn examples. There are data dumps of a bunch of examples. This is an example of "training" our data. If we have a decently sized database, then we are ready to try to compare some numbers. A good idea would be to hand-draw an example for your program to compare to. To compare, we'd just simply do the same thing to the question-image. We'd threshold the image into black or white pixels, then we take that pixel list, and compare it to all of our examples. In the end, we will have so many possible "hits." Whichever character has the most "hits" is likely to be the correct one. Done, we've recognized that image. If you think about it, this is actually very similar to how we humans recognize things. Naturally, many children do not immediately distinguish between couches and love seats. What is the difference many of them ask. There is a bit of a grey area between them, and they have many similarities. Generally, a lot of learning comes by example. After seeing hundreds of couches, thousands of chairs, and hundreds of love-seats, a person soon begins to easily distinguish between them, because they have quite a bit of sample data to compare to. This is even how we read text. A number 5 really does mean nothing to a baby. They only begin to learn what a number 5 is as they are shown it over and over, being told it is "5." Eventually, they understand that to be a 5, and they can see 5 in multiple font types and still recognize it to be a 5. Sentdex.com Facebook.com/sentdex Twitter.com/sentdex

Template Matching - OpenCV with Python for Image and Video Analysis 11
Welcome to another OpenCV with Python tutorial, in this tutorial we're going to cover a fairly basic version of object recognition. The idea here is to find identical regions of an image that match a template we provide, giving a certain threshold. For exact object matches, with exact lighting/scale/angle, this can work great. An example where these conditions are usually met is just about any GUI on the computer. The buttons and such are always the same, so you can use template matching. Pair template matching with some mouse controls and you've got yourself a web-based bot! To start, you will need a main image, and a template. You should take your template from the exact "thing" you are looking for in the image. I will provide an image as an example, but feel free to use an image of your favorite website or something like that.

K-means & Image Segmentation - Computerphile

Fire Pong in Detail: https://youtu.be/ZoZMMg1r_Oc Deep Dream: https://youtu.be/BsSmBPmPeYQ FPS & Digital Video: https://youtu.be/yniSnYtkrwQ Dr. Mike's Code: % This script is the one mentioned during the Computerphile Image % Segmentation video. I chose matlab because it's a popular tool for % quickly prototyping things. Matlab licenses are pricey, if you don't have % one (or, like me, work for an organisation that does) try Octave as a % good free alternative. This code should work in Octave too. % Load in an input image im = imread('C:\Path\Of\Input\Image.jpg'); % In matlab, K-means operates on a 2D array, where each sample is one row, % and the features are the columns. We can use the reshape function to turn % the image into this format, where each pixel is one row, and R,G and B % are the columns. We are turning a W,H,3 image into W*H,3 % We also cast to a double array, because K-means requires it in matlab imflat = double(reshape(im, size(im,1) * size(im,2), 3)); % I specify that initialisation shuold sample points at % random, rather than anything complex like kmeans++ initialisation. % Kmeans++ takes a long time if you are using 256 classes. % Perform k-means. This function returns the class IDs assigned to each % pixel, and in this case we also want the mean values for each class - % what colour is each class. This can take a long time if the value for K % is large, I've used the sampling start strategy to speed things up. % While KMeans is running, it will show you the iteration count, and the % number of pixels that have changed class since last iteration. This % number should get lower and lower, as the means settle on appropriate % values. For large K, it's unlikely that we will ever reach zero movement % (convergence) within 150 iterations. K = 3 [kIDs, kC] = kmeans(imflat, K, 'Display', 'iter', 'MaxIter', 150, 'Start', 'sample'); % Matlab can output paletted images, that is, grayscale images where the % colours are stored in a separate array. This array is kC, and kIDs are % the grayscale indices. colormap = kC / 256; % Scale 0-1, since this is what matlab wants % Reshape kIDs back into the original image shape imout = reshape(uint8(kIDs), size(im,1), size(im,2)); % Save file out, you need to subtract 1 from the image classes, since once % stored in the file the values should go from 0-255, not 1-256 like matlab % would do. imwrite(imout - 1, colormap, 'C:\Path\Of\Output\Image.png'); http://www.facebook.com/computerphile https://twitter.com/computer_phile This video was filmed and edited by Sean Riley.

Detecting and Recognizing Text in Natural Images
Text in natural images possesses rich information for image understanding. Detecting and recognizing text facilitates many important applications. From a computer vision perspective, text is a structured object made of characters arranged in a line or curve. The unique characteristics of text makes its detection and recognition problems different than that of general objects. In the first part of this talk, I will introduce our recent work on text detection, where we decompose long text into smaller segments and the links between them. A fully-convolutional neural network model is proposed to detect both segments and links at different scales in a single forward pass. In the second part, I will introduce our work on text recognition, where we tackle the structural recognition problem with an end-to-end neural network that outputs character sequences from image pixels. We further incorporate a learnable spatial transformer into this network, in order to handle text of irregular shape with robustness.  See more at https://www.microsoft.com/en-us/research/video/detecting-and-recognizing-text-in-natural-images/

Morphological Transformations - OpenCV with Python for Image and Video Analysis 9
In this OpenCV with Python tutorial, we're going to cover Morphological Transformations. These are some simple operations that we can perform based on the image's shape. These tend to come in pairs. The first pair we're going to talk about is Erosion and Dilation. Erosion is where we will "erode" the edges. The way these work is we work with a slider (kernel). We give the slider a size, let's say 5 x 5 pixels. What happens is we slide this slider around, and if all of the pixels are white, then we get white, otherwise black. This may help eliminate some white noise. The other version of this is Dilation, which basically does the opposite: Slides around, if the entire area isn't black, then it is converted to white.

OpenCV Face Detection with Raspberry Pi - Robotics with Python p.7
Next, we're going to touch on using OpenCV with the Raspberry Pi's camera, giving our robot the gift of sight. There are many steps involved to this process, so there's a lot that is about to be thrown your way. If at any point you're stuck/lost/whatever, feel free to ask questions on the video and I will try to help where possible. There are a lot of moving parts here. If all else fails, I have hosted my Raspberry Pi image: https://drive.google.com/file/d/0B11p78NlrG-vZzdJLWYxcU5iMXM/view?usp=sharing OpenCV stands for Open Computer Vision, and it is an open source computer vision and machine learning library. To start, you will need to get OpenCV on to your Raspberry Pi. http://mitchtech.net/raspberry-pi-opencv/ Keep in mind, the "make" part of this tutorial will take 9-10 hours on a Raspberry Pi Model B+. The Raspberry Pi 2 will do it in more like 2-4 hours. Either way, it will take a while. I just did it overnight one night.
