K-means & Image Segmentation - Computerphile
K-means sorts data based on averages. Dr Mike Pound explains how it works. 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.

How Hough Transform works
In this video I explain how the Hough Transform works to detect lines in images. It firstly apply an edge detection algorithm to the input image, and then computes the Hough Transform to find the combination of Rho and Theta values in which there is more occurrences of lines. This algorithm can also be applied to detect circles, but I only presented a visual example of the algorithm to detect lines. To create the animation I used octave 4, and packages image and geometry.

Image Operations - OpenCV with Python for Image and Video Analysis 4
In this Python with OpenCV tutorial, we're going to cover some of the basics of simple image operations that we can do. Every video breaks down into frames. Each frame, like an image, then breaks down into pixels stored in rows and columns within the frame/picture. Each pixel has a coordinate location, and each pixel is comprised of color values. Let's work out some examples of accessing various bits of these principles.

A machine learning approach for 3D shape analysis and recognition of archaeological objects
Museum professionals all over the world have always shown great interest in acquiring automatic methods to register and analyse the shape of cultural heritage artefacts. Thanks to recent advances in 3D scanning and photogrammetry techniques, it is now possible to model the surface of objects with very little effort and in a relatively short time. The continuous adoption of these techniques in cultural institutions has generated thousands if not millions of 3D digital models. Unfortunately, after these resources are produced, very little effort is spent in making them accessible to researchers or the general public. Part of the problem is a lack of efficient computer mechanisms to search, retrieve and classify 3D data. The conventional way to search and retrieve 3D models consists in composing a query based on text descriptions. However, textual annotations are necessarily constrained by the database application domain, ontology, etc., as well as by language and other factors. Consequently they are inadequate for shape oriented searches. This paper presents results of an on-going project focused on developing a computer platform to automatize the search, retrieval, recognition and analysis of 3D object models. The platform processes queries based on geometric properties instead of text. Simply stated, the computer program takes a 3D surface mesh as input (i.e. the query model). Then, a search engine compares it to hundreds or even thousands of 3D scanned objects stored in a repository identifying those that approximate the shape of the query model. Next, the matching models are retrieved, ranked by degree of similarity and displayed to the final user. Afterwards, additional tools can be deployed to perform some kind of analysis on the objects retrieved. A platform like this is much more powerful than a text search engine because it avoids mismatching situations, such as when a person queries the database looking up for "bowls" and retrieves nothing just because the bowls are labelled as "cuencos" (a Spanish term) or "cajetes" (i.e. a term common in Mesoamerican archaeology to described the same type of vessels). Moreover, the platform is able to exploit mathematical analysis algorithms for automatic classification of shapes. During the presentation, we discuss the specific requirements that a shape recognition platform must satisfy to be useful in museums and cultural heritage research. In archaeological projects, for example, we encounter objects that are not necessarily identical in terms of geometry and yet they are considered to belong to the same class. We also intent to show the first part of this platform, namely the search engine for matching and retrieval of 3D Objects.

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.

Haar Cascade Object Detection Face & Eye - OpenCV with Python for Image and Video Analysis 16
In this OpenCV with Python tutorial, we're going to discuss object detection with Haar Cascades. We'll do face and eye detection to start. In order to do object recognition/detection with cascade files, you first need cascade files. For the extremely popular tasks, these already exist. Detecting things like faces, cars, smiles, eyes, and license plates for example are all pretty prevalent. First, I will show you how to use these cascade files, then I will show you how to embark on creating your very own cascades, so that you can detect any object you want, which is pretty darn cool! You can use Google to find various Haar Cascades of things you may want to detect. You shouldn't have too much trouble finding the aforementioned types. We will use a Face cascade and Eye cascade. You can find a few more at the root directory of Haar cascades. Note the license for using/distributing these Haar Cascades. text-based tutorial and sample code: https://pythonprogramming.net/haar-cascade-face-eye-detection-python-opencv-tutorial/ https://pythonprogramming.net https://twitter.com/sentdex https://www.facebook.com/pythonprogramming.net/ https://plus.google.com/+sentdex

However, current fingerprint-based biometric systems are vulnerable to spoofing attacks. Moreover, single feature-based static approach does not perform equally over different fingerprint sensors and spoofing materials. In this paper, we propose a static software approach. We propose to combine low-level gradient features from speeded-up robust features, pyramid extension of the histograms of oriented gradient and texture features from Gabor wavelet using dynamic score level integration. We extract these features from a single fingerprint image to overcome the issues faced in dynamic software approaches, which require user cooperation and longer computational time. A experimental analysis done on LivDet 2011 data produced an average equal error rate (EER) of 3.95% over four databases. The result outperforms the existing best average EER of 9.625%. We also performed experiments with LivDet 2013 database and achieved an average classification error rate of 2.27% in comparison with 12.87% obtained by the LivDet 2013 competition winner.

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.
