In my previous three articles (1,2,3) I discussed how to use Canny edge detection and Hough transform to identify blur […]
Image Blur Detection via Hough Transform — III
I will continue where I left off in my previous post. After performing Hough transform, and extracted the longest sections […]
Image Blur Detection via Hough Transform — II
In my previous post, I briefly discussed the rationale behind automated blur detection in digital imagery and did an overview […]
Image Blur Detection via Hough Transform — I
It is often necessary to identify and classify images based on their clarities. For instance, it is desirable for an […]

Two Level Tree and Its Applications — II
In my previous post, I discussed how to merge and split a two level tree. Before moving on to discuss […]
Two Level Tree and Its Applications — I
A two level tree is a simple tree data structure. Unlike in a typical tree where the tree depths could […]
Producer-Consumer: A Duplicate File Finder
Processes tend to benefit greatly from multi-core processors if they are CPU bound (i.e. computational intensive tasks). The actual speedup […]
Same Method, Different Speed
I came across something rather interesting the other day when trying to determine what sorting algorithms .Net Framework uses in […]
