The Deceived Weighted Filter Framework (DeWAFF) is a set of filters designed to achieve image abstraction, which refers to the enhancement of perceptually important details of an image such as edges and contrast, and the simplification of less important information like noise and textures. In this talk, the presenter will refer to his experience of implementing the DeWAFF as a preprocessing stage in biomedical processing image system designed for cell segmentation and tracking pipeline. Such system is part of an ongoing research project in collaboration with Dr. Rodrigo Mora and Dr. Steve Quirós, microbiologists at the Chemo-sensibility Laboratory, University of Costa Rica. The presentation present different image processing research challenges tackled and still open. Finally, the presentation will address other biomedical related project initiatives of interest, to finally open the discussion of important challenges in the exciting field of biomedical digital image processing.
