Functional template-based SAR image segmentation

We present an approach to automatic image segmentation, in which user selected sets of examples and counter-examples supply information about the speci/c segmentation problem. In our approach, image segmentation is guided by a genetic algorithm which learns the appropriate subset and spatial combination of a collection of discriminating functions, associated with image features. The genetic alg...

Image Segmentation Based on Fast Normalized Cut

In this paper, we propose a fast image segmentation method based on normalized cut. This method apply simple linear iterative clustering super-pixel algorithm to obtain super-pixel regions, and then use affinity propagation clustering to extract the representative pixels in each super-pixel regions, Finally, we apply normalized cut to obtain segmentation results. At the end of the paper, Numeri...

Despeckle-based SAR Image Compression

Abstract— SAR images suffer from speckle noise that degrades image quality. Speckle removal is to be applied when signatures such as edges and fields have to be extracted from the image; speckle removal is also needed for image compression as such noise increases image entropy. Nevertheless, most lossy compression skims act as low pass filters that do not fit multiplicative noise reduction. In ...

Multiregion Graph Cut Image Segmentation

The purpose of our study is two-fold: (1) investigate an image segmentation method which combines parametric modeling of the image data and graph cut combinatorial optimization and, (2) use a prior which allows the number of labels/regions to decrease when the number of regions is not known and the algorithm initialized with a larger number. Experimental verification shows that the method resul...

Image Segmentation with Ratio Cut

This paper proposes a new cost function, cut ratio, for segmenting images using graph-based methods. The cut ratio is defined as the ratio of the corresponding sums of two different weights of edges along the cut boundary and models the mean affinity between the segments separated by the boundary per unit boundary length. This new cost function allows the image perimeter to be segmented, guaran...
