Fast image and video denoising via nonlocal means of similar neighborhoods
In this note, improvements to the non-local means image denoising method introduced in [2], [3] are presented. The original non-local means method replaces a noisy pixel by the ...

Feature Reduction and Hierarchy of Classifiers for Fast Object Detection in Video Images
We present a two-step method to speed-up object detection systems in computer vision that use Support Vector Machines (SVMs) as classifiers. In a first step we perform feature red...

Exploiting local auto-correlation function for fast video to reference image alignment
Digital images of natural scenes are usually characterized by strong spatial correlation between adjacent pixels which has been successfully exploited in the coding of still and m...
