Based on high-resolution remote sensing images and the eCognition Developer platform, the research described in this paper makes full use of the rich spectral, spatial, textural and feature geometry information contained in high-resolution images acquired from Quickbird. The object-oriented, multiscale segmentation method as well as the nearest neighborhood and membership function classification methods...
A vision based method of vehicle detection was proposed. Firstly, a improved common region algorithm to realize the background subtraction which having a better robustness and easy to determine the background image real timely. Then a threshold segmentation method is used in object extraction stage. Compared with the existing algorithm, such an iterative algorithm based on weighted average of thresholds...
Both of face detection and Face recognition play important role in the technology of biologic character identify. During processing of face image, it is indispensable to pre-processing. In this paper, a Pre-processing method for face color image based on rough sets theory is put forward. In this method, the image is divided as foreground and background by condition attribution. In order to extract...
An algorithm based on Dempster-Shafer evidence theory with discernment frame segmentation is proposed for texture image analysis, which applies to automatic gradation of spherular pearlite about 15CrMo. Image enhancement, segmentation and feature extraction is implemented first to form the feature space, which includes the fractal dimension, energy and entropy. The feature information is fused using...
