Curvelet Analysis

This blog post is a continuation of my previous post on ridgelet analysis. Motivated by the problem of finding efficient representation of objects, people introduced yet another representation system called the curvelet transform. This is very efficient in representing objects that have discontinuities along curves, and compressing image data as well. Curvelets are a non-adaptive technique … Continue reading Curvelet Analysis

OpenCV On Mac: How To Get It Up And Running?

OpenCV is a computer vision library used extensively by people in the computer vision field. Until a couple of years ago, OpenCV was a bit hacky and the usage was not very straightforward. But determined efforts by multiple companies finally standardized the process and now it is nice and clean. Computer vision algorithms are computationally … Continue reading OpenCV On Mac: How To Get It Up And Running?

What Does Backpropagation Mean?

People started working on artificial intelligence back in the late '60s. After they came up with the concept of perceptron, this field looked very promising. But as the years passed by, no significant development took place even after making several attempts from multiple directions! As people were beginning to lose hope, backpropagation came into picture … Continue reading What Does Backpropagation Mean?
