I have computed PCA using the following : function [signals,V] = pca2(data) [M,N] = size(data); data = reshape(data, M*N,1); % subtract off the mean for each dimension mn = mean(data,2); data = bsxfun(@minus, data, mean(data,1)); % construct the matrix Y Y = data'*data / (M*N-1); [V D] = eigs(Y, 10); % reduce to 10 dimension % project the original data signals = data * V; My question is: Is "signals" is the projection of the training set into the eigenspace? I saw in "Amir Hossein" code that "centered image vectors" that is "data" in the above code needs to be projected into the "facespace" by

cap = cv2.VideoCapture(0) is not opening web camera when executing the command in Google Colab. Since Colab is running in your browser, you'll want to use web APIs to access local hardware like a camera. Here's an example showing how to capture an image from your local webcam in Colab: https://colab.research.google.com/notebooks/snippets/advanced_outputs.ipynb#scrollTo=2viqYx97hPMi 来源： https://stackoverflow.com/questions/54389727/how-to-use-cap-cv2-videocapture0-in-google-colab

I am able to detect faces using open cv but I don't know how to process face recognition. I googled a lot but I didn't find any articles or blogs that can guide me. Can someone help me to develop face recognition App in android? Telmo You can always use JavaCV that is a kind of wrapper for the native OpenCV functions: See: Face Recognition on Android In order to get everything working you have to extract some .so files to your libs folder in the project: Follow the instructions on this page Go to File > New > Folder, select your project as parent folder, type "libs/armeabi" as Folder name, and

I am trying to develop an iPhone for Face recognition/detection. In my app i want to make my iPhone camera should be auto focused and auto capture. How to recognition the face from iPhone app? It is possible to auto focus the face and auto capture in our iPhone app. If it is possible can anyone please help to do this? I just want any suggestion/ideas and tutorials about that. Can you please help me? Thanks in advance. Core Image has a new CIFaceDetector to detect faces in real time; you can start with these examples to take an overview: SquareCam iOS Facial Recognition Easy Face detection with

Does anybody know which,currently,is the best library for realizing a real time face-tracking solution for iPhone? I've done a research but I've found quite old articles about OpenCV portings. I would like to know if there is any specific,reliable,fast (and possibly free) AR solution for overlay in real time an image to the face in iPhone camera Video Stream (not simply a static image) Any help (link,tutorial) would be great. Thanks everybody!! Elos iOS 5 brings facial recognition as a native feature. Basically you just have to configure an object to act as your the video output stream’s

I have a very large photo gallery with thousands of similar people, objects, locations, things. The majority of the people in the photos have their own user accounts and avatar photos to match. There are also logical short lists of people potentially in the photo based on additional data available for each photo. I allow users to tag photos with their friends and people they know but an automated process would be better. I've used photo tagger/finder from face.com integrating with Facebook photos and the Google Picasa photo tagger for personal albums also does the same thing and is exactly
