A new method is proposed to perform selective smoothing of images affected by speckle noise.A new smoothing criterion is defined for the average smoothing filter.The convolution window of the smoothing filter is adjustable.The method is evaluated usi

In this work, a method to enhance images based on a new artificial life model is presented. The model is inspired on the behavior of a herbivore organism, when this organism is in a certain environment and selects its food. This organism travels thro

The manifestation of pathogens in plantations is the most important cause of losses in several crops. These usually represent less income to the farmers due to the lower product quality as well as higher prices to the consumer due to the smaller offe

Speckle noise strongly affects the images acquired by ultrasound scans and reduces the efficiency of computational methods to extract and understand the features presented in the images. Trying to overcome this problem, a selective denoising method i
