The work aims at enhancing the photoelectrochemical performance of photoelectrode from two aspects: The TiO2 NTWs is manufactured by anodic oxidation method and then annealed in hydrogen atmosphere. The as-prepared materials are sensitized with PbS and CdS quantum dots via successive ion layer absorption method (SILAR) method. The as-prepared materials are characterized by scanning electron microscope(FESEM),...
Image segmentation is a basic task in image analysis and understanding and feature extraction is important but difficult. In this paper, we propose an effective feature selection method for color image segmentation which selects a group of mixed color features or channels from some different color spaces according to the principle of the least entropy of pixels frequency histogram distribution. Actually,...
