The Extrema Edges
نویسندگان
چکیده
We present a new approach to model edges in monochrome images. The method is divided in two parts: the localization of possible edge points and their valuation. The first part is based on the theory of minimal paths, where the selection of an energy and a set of sources determines a partition of the domain. Then, the valuation is obtained by the creation of a contrast driven hierarchy of partitions. The method uses only the original image and supplies a set of closed contours that preserve semantically important characteristics of edges.

Edge-preserving Multiscale Image Decomposition based on Local Extrema Citation
We propose a new model for detail that inherently captures oscillations, a key property that distinguishes textures from individual edges. Inspired by techniques in empirical data analysis and morphological image analysis, we use the local extrema of the input image to extract information about oscillations: We define detail as oscillations between local minima and maxima. Building on the key o...
متن کاملFast Image Edge Detection based on Faber Schauder Wavelet and Otsu Threshold
Edge detection is a critical stage in many computer vision systems, such as image segmentation and object detection. As it is difficult to detect image edges with precision and with low complexity, it is appropriate to find new methods for edge detection. In this paper, we take advantage of Faber Schauder Wavelet (FSW) and Otsu threshold to detect edges in a multi-scale way with low complexity,...
متن کاملEdge-preserving Wavelet Image Representations with Applications to Compression of Aerial Ortho Images
This paper describes a new second-generation-type lossy image compression scheme using wavelets for aerial ortho images. For map applications where some losses are allowed, aerial ortho images present a possibility of having a very high compression ratio, because they are natural images with many uniform (coherent) subregions. However classical compression schemes such as the joint-photograph e...

The qualitative structure of images is much like the quali tative structure of landscapes Critical points of a landscape are the summits the immits and the saddle points These points are connected through special curves on the surface of the landscape The new approach computes this basic qualitative structure of an image or a landscape from the neighborhood structure of a sampled grid by a proc...
متن کاملImage segmentation and analysis via multiscale gradient watershed hierarchies
Multiscale image analysis has been used successfully in a number of applications to classify image features according to their relative scales. As a consequence, much has been learned about the scale-space behavior of intensity extrema, edges, intensity ridges, and grey-level blobs. We investigate the multiscale behavior of gradient watershed regions. These regions are defined in terms of the g...
