Multimedia content description interface (MPEG-7) includes a number of image feature descriptors to represent low-level image features such as colors, textures and shapes effectively. But, the contribution of each descriptor may not be the same for a domain specific image database when computing the similarity measure. Machine learning techniques for the optimization of feature descriptor weights...
In image annotation system, performance is highly desired. We use a bi-coded chromosome-based genetic algorithm to optimize the weights of multimedia content description interface (MPEG-7) feature descriptors and select optimal feature descriptor subset simultaneously. Two genetic codes are used: a real code represents the weights corresponding to MPEG-7 descriptors; a binary one denotes the presence...
