The paper presents novel modifications to radial basis functions (RBFs) and a neural network based classifier for holistic recognition of the six universal facial expressions from static images. The new basis functions, called cloud basis functions (CBFs) use a different feature weighting, derived to emphasize features relevant to class discrimination.(More)
Given the limitations of human perceptions it would be impossible to classify the images manually. The IRIS (Image Retrieval and Indexing System for Data Mining) that we have developed is a solution to this problem. Numerous research attempts have made at various levels trying to solve the inherent issues. “QBIC” (Query by Image Content) system of IBM [1](More)
