Abstract

Texture analysis is a classic yet still challenging task in computer vision, for which artificial neural networks are actively being applied. Most approaches take advantage of large and complex architectures of convolutional neural networks trained with huge databases and that demand high processing power. In contrast to these approaches based on complex architectures, Randomized Neural Networks (RNNs) can provide texture descriptors based on a simple representation learning paradigm that has low computational cost (thanks to training based on a closed-form solution), which uses few data and is easy to interpret. In this sense, this project aims to study, implement and develop improvements in techniques for learning texture representations using Randomized Neural Networks, in order to extract rich representations with low computational cost and using few data. In addition, the texture analysis methods studied and developed will be applied to microscopy images (such as sensory units and tissues) with the purpose of diagnosing diseases. Thus, it is expected that this research results in contributions in the computational scope with improved techniques for texture analysis and also related to the areas of applications with better performance in disease diagnoses. It should be noted that these contributions are congruent with the objectives of the thematic project (process, 2018/22214-6) of which this project is part, whose goal is the convergence of technologies for diagnosis.
