During the last decade, Active Contour Models had been greatly developed and were used in image edge detection, image segmentation and classification, image registration, 3D reconstruction and many other areas. In the meantime, Active Contour Models themselves had also been enriched and completed. Various typed Active Contour Models had emerged, such as Sobolev Active Contour Model(SACM). SACM was...
Aimed at the characteristic of metallographical image, a specific image, and based on the multi-structural element in the mathematical morphology, a new method of edge detection is proposed in this paper to deal properly with the double- boundary and the inaccuracy of the boundary localization in the image in the edge detection carried by the traditional edge detection method, such as Roberts, Sobel,...
This paper proposes a novel algorithm which simultaneously inpaints structures and textures of damaged images. In past years, people copy the pixels, which come from the surrounding neighborhood or selected example, into damaged region along isophate direction. This might cause such result as blur edges, which looks "unreasonable" to human eyes. This algorithm decomposes the image into two...
This paper is a research on unsupervised texture segmentation technique using Gabor filters and multi-PCNN. The partitioning method based on Gabor filters gets the good segmentation result, but causes the huge data. PCNN is a parallel way and can be easily realized with hardware, especially VLSI, which makes PCNN process image fast. We present an algorithm which uses Gabor filters to extract image...
