Acceleration of filtering and enhancement operations through geometric processing of gray-level images

M.A. Garcia, B.X. Vintimilla
Proceedings 2000 International Conference on Image Processing (Cat. No.00CH37101)  
This paper describes an algorithm to implement image filtering and enhancement operations by processing adaptive triangular meshes that represent gray-level images.  ...  Experimental results show that these operations are significantly more efficient when they are performed upon triangular meshes than by sequentially processing all the pixels contained in the given images  ...  The same filtering and enhancement operations have been applied to the original gray-level images by using the public image processing library CVIPtools [10] .  ...
