Trying to demonstrate how to do data augmentation on the KITTI stereo dataset, I found myself diving (too deeply) into Blender 3D.What I set out to do is add a 3D object to an unsuspecting image from the KITTI dataset, to show that one way to get more training data is by synthesizing. I just put a 3D object in front of an image (say a 3D plane with the image as the texture) and done ✅ I ve augmented the image. Turns out it needs a bit more of Blender trickery. This is the real reason for this post.I ve seen people request a plugin for OBS to remove background (aka Matting) from their camera input. It s a standard in all video conferencing software today! I also was recording some screencasts with OBS with my video in the corner, and it became instantly obvious how much I need this feature in OBS So I set out to create one.Got an hour-long video and not really into manually creating subtitles? not plans to put it on YouTube for their automated transcription services? then try Google Cloud Speech-to-Text! In this post I ll share some scripts for automating the process and creating an .str file to go along your video for displaying the subtitles.ImageMagick has a built in Montage creating tool. It s good enough for casual montaging, but it s definitely suboptimal for packing varying size images.I m very excited to announce the publication of my latest Mastering OpenCV book!With many new chapters and all the others re-written practically from scratch, this edition is by far the best ever.The excellent David Millán Escrivá and I go deep and wide across the range of capabilities of OpenCV, explaining the theory and implementing recent real-world vision tasks from the ground up.It s been baking for many months in the oven, rising slowly, and finally ready for consumption yum!The sources are free to grab: https://github.com/PacktPublishing/Mastering-OpenCV-4-Third-EditionAnd copies are available onAmazon: https://amzn.to/2Ff1mmEPackt: https://www.packtpub.com/application-development/mastering-opencv-4-third-edition?utm_source=github utm_medium=repository utm_campaign=9781789533576Enjoy reading!Hey-oJust sharing a code snippet to warp images to cylindrical coordinates, in case you re stitching panoramas in Python OpenCV This is an improved version from what I had in class some time ago It runs VERY fast. No loops involved, all matrix operations. In C++ this code would look gnarly.. Thanks Numpy!Enjoy!Roy Reporting on a project I worked on for the last few weeks porting the excellent Gesture Recognition Toolkit (GRT) to Python.Right now it s still a pull request: https://github.com/nickgillian/grt/pull/151.Not exactly porting, rather I ve simply added Python bindings to GRT that allow you to access the GRT C++ APIs from Python.Did it using the wonderful SWIG project. Such a wondrous tool, SWIG is. Magical.Here are the deetsContinue reading Take a SWIG out of the Gesture Recognition Toolkit (GRT) This is my first trial at using Jupyter notebook to write a post, hope it makes sense.I ve recently taught a class on generative models: http://hi.cs.stonybrook.edu/teaching/cdt450In class we ve manipulated face images with neural networks.One important thing I found that helped is to align the images so the facial features overlap.It helps the nets learn the variance in faces better, rather than waste their representation power on the shift between faces.The following is some code to align face images using the excellent Dlib (python bindings) http://dlib.net. First I m just using a standard face detector, and then using the facial fatures extractor I m using that information for a complete alignment of the face.After the alignment I m just having fun with the aligned dataset
