Video Lectures and Talks. Saturday, March 9, 2013. Reading and Writing cv: Mat in OpenCV in C. In C api for OpenCV, you often come across writing and reading matrices as text files (analogous to saving .mat files in MATLAB/Octave). This is a simple way of doing it. You could even save multiple matrices in a single .xml/.yaml. However, I couldn't find ways to read more than 1 matrix which was written to file and being read using Python API. Posted by Rahul Kavi. Matrix types in using imshow and imwrite.

DeveloperStation.ORG: very basic intro to Caffe
http://www.developerstation.org/2015/08/intro-to-caffe-tutorial.html
Video Lectures and Talks. Monday, August 10, 2015. Very basic intro to Caffe. This tutorial just gives you a basic idea of what Caffe can do (not for advanced use of Caffe through defining your own layers, using C /Python API) for defining your own network to solve a Computer Vision task. I'm assuming you already have a background in Machine Learning, Statistical Pattern Recognition and have built Neural Networks in the past using some programming language. Create train.txt and test.txt with file...You t...

Video Lectures and Talks. Wednesday, February 5, 2014. Fun with my Raspberry Pi. I ordered a Raspberry Pi recently. I've heard so much about this device in the recent past, I decide to try it out. I was reminded of few microprocessor(fun class) and electrical engineering(not so fun time) classes that I took in my undergrad. I wrote a simple program that could turn a Stepper Motor using a motor controller. Connected to a Raspberry Pi. HDMI cable to connect to a TV or monitor. For powering the stepper motor.

DeveloperStation.ORG: simple Convolutional Neural Net based object recognition
http://www.developerstation.org/2016/03/simple-convolutional-neural-net-based.html
Video Lectures and Talks. Wednesday, March 9, 2016. Simple Convolutional Neural Net based object recognition. I made a simple object recognition module over the last weekend. I wrote a Theano. Based convolutional neural network. I wrote a simple OpenCV. Based image segmentation program. The output from the image segmentation program is passed to the Theano based Convolutional Neural Network. I used 10,000 images for training and 16,000 images for testing. Posted by Rahul Kavi. On the way to Virtual World.

Video Lectures and Talks. Sunday, June 9, 2013. Logisitic Regression in OpenCV. I finished writing a Logistic Regression classifier in OpenCV. I've seen a lot of posts on the web asking for OpenCV's version of the same but its not available. Its easy to write your own logistic regression classifier. I separated out the cost function and gradient descent algorithm (Batch Gradient Descent). You can replace it with your own optimization algorithm. I posted it on my Github page. You can check it out:.

Video Lectures and Talks. Sunday, March 13, 2016. Simple Autoencoder on MNIST dataset. So, I had fun with Theano and trained an Autoencoder on a MNIST dataset. More about Autoencoders is available here. More variants of Autoencoders exist (Sparse, Contractive, etc.) are available with different constraints on the hidden layer representation. I trained an vanilla Autoencoder for 100 epochs with 16 mini batch size and learning rate of 0.01. Posted by Rahul Kavi. Wednesday, March 9, 2016. The output from th...

Video Lectures and Talks. Tuesday, December 16, 2014. Machine Learning is also provided in this book along with code samples. Code samples for classifiers such as KNN, Random Forest, SVM are provided. I'm glad that steps to configure GPU (CUDA), a couple of GPU optimized OpenCV programs using NVIDIA CUDA are also provided. If you are looking for a decent book for OpenCV with most recent stable release (2.4.9) covered, this is a good buy. You can purchase it here. Posted by Rahul Kavi. The robot would ste...
