Increasing demand for a fast and reliable face recognition technology has obliged researchers to try and examine different pattern recognition schemes. But until now, Genetic Programming (GP), acclaimed pattern recognition, data mining and relation discovery methodology, has been neglected in face recognition literature. This paper tries to apply GP to face recognition. First Principal Component Analysis (PCA) is used to extract features, and then GP is used to classify image groups. To further improve the results, a leveraging method is also utilized. It is shown that although GP might not be efficient in its isolated form, a leveraged GP can offer results comparable to other Face recognition solutions
As the performance gap between memory systems and processors has increased, virtual memory management plays an important role in system performance. Different caching policies have different effects on the system performance. This paper studies an adaptive replacement policy which has low overhead on system and is easy to implement. Simulations show that our algorithm performs better than Least-Recently-Used (LRU) and Least-Frequently-Used (LFU). In addition, it performs similarly to LRU in worst cases.

This work deals with textural segmenting of high resolution sidescan sonar images by using active contours and Gabor filters. In fact this method is a modification of Chan and Vese Active contour model. It makes the method suitable for textural segmenting of above said images. First, image is passed through a symmetric bank of Gabor filters. Then, filtered images that possess a significant component of the original image are subjected to morphological closing operator. At the end, we use multi channel C-V active contour model for segmenting areas with different textures. Results of the proposed method are presented for different real and simulated sidescan sonar images to demonstrate the robustness of it.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
