Memetic Algorithm (MA) is a meta-heuristic algorithm which combines an Evolutionary Algorithm (EA) and a local search algorithm. In this work, we design a cooperate memetic algorithm (CMA) for image retrieval. We propose a novel image indexing method based on YCbCr color space and 4096-tree. And then we describe the memetic algorithm with local search chain and cooperate memetic algorithm (MA-LSCH-CMA)...
Color, texture and shape information have been the primitive image descriptors in content based image retrieval systems. However, how to quickly retrieving images is a challenge because that the speed and efficiency of retrieving image from Internet image is most important. We used genetic algorithm to improve the method based on HSV color space, and optimized the computational workload. First, the...
How to quickly retrieval the image is a very action research topic in the research of image retrieval based on Internet because of the large amount of data required by images. We propose a novel image indexing method based on YCbCr color space and design a system to improve retrieval efficiency. The main focus of this study is dimensionality reduction and image index of Web image. First, the paper...
The contents-based image retrieval (CBIR) is general type of retrieval which has been an active area of research for many years. How to quickly retrieval the image is a very action research topic in the research of image retrieval based on Web because of the large amount of data required by images. Therefore automatic and efficient indexing is needed for fast content based retrieval, it alleviates...
How to find out a particularly efficient search algorithm in the premise of a considerable accuracy is highlighted in the research of Web content-based image retrieval. This paper focuses on dimensionality reduction and similarity measure of Web image. First, the paper presents the current commercial search engines how to look for Web images. Then, it describes commonly used methods for the non-linear...
How to reduce more of the image dimensions without losing the main features of the image is highlighted in the research of Web content-based image retrieval. This paper started by analysis of commonly used methods for the dimension reduction of Web images, followed by proposing dimensionality reduction method that is based on HSV features, where the HSV color histogram intersection was used as the...
