The friction welding supersonic C scanned pictures will introduce the noise in process of gatherring and conversion, and the disturbance of the noise to the image effects image's quality, which brought the enormous difficulties for image characteristic information extraction and analysis. Therefore, this article will propose a denoising analysis method, which obtains the scanned picture to the experiment...
Considering the requirements of real time and robustness for the segmentation algorithms for mobile robots, an optimal threshold segmentation algorithm based on mathematical morphology was studied. Two improved measures, i.e., introducing an improved combination filter of median and multi-scale, and increasing morphological opening and closing operation, were proposed for the general optimal threshold...
With the development and applications of satellite remote sensing technology, the edge detection accuracy of remote sensing image is increasingly high. As the gray remote sensing image has a lot of noise, even image brightness, and vague edge, a novel edge detection algorithm based on cellular neural network (CNN) is presented In the algorithm, image filtering, gray threshold segmentation, dilation...
