Haar-Cascade of Classifiers

1 What is it? 1.1 It's a Feature-based AdaBoost Machine Learning technique proposed by Paul Viola and Michael Jones in their paper, "Rapid Object Detection using a Boosted Cascade of Simple Features" in 2001 2 How does it work? 2.1 Generate simple features like vertical or horizontal subtraction boxes. The feature is their subtracted values... Continue Reading →

Local Maximal and Fourier Transform

This blog presents a novel way of returning local maximal number and its index and maximal pattern matching in different lists. Then, I discusses the relationship between local maximal and the Fourier Transform. An intuitive algorithm to return local maximal and compare pattern in maximal appearance. The relationship between local maximal and the Fourier Transform

Recursive BTPT in Python

Today I uploaded my first solution on Leetcode. Cheers! Here is the content~ Explanation: Recursive programming is easy and straightforward. Base condition: return [](empty list) when input is None. Step condition: if input is not None, append current node's value to the rList. And then proceed to Pre-traversal the Left and the Right. In this... Continue Reading →
