Non-additive Approach for Omnidirectional Image Gradient Estimation
The way catadioptric images are acquired implies that they present radial distortions. Therefore, classical processing may not be suitable. This statement will be illustrated by c...

A SR-based radon transform to extract weak lines from noise images
The Radon transform is able to transform two dimensional images with lines into a space of line parameters, where each line in the image will give a peak positioned at the corresp...
