Edge is a basic feature of image. The image edges include rich information that is very significant for obtaining the image characteristic by object recognition. Edge detection refers to the process of identifying and locating sharp discontinuities in an image. So, edge detection is a vital step ...
3)结构边缘检测包括: SE (structured forests edge detection) algorithm [10]。 虽然手工设计的算法已经成果显著,但其限制也是很明显的。 基于深度学习 的方法:2015 HED [12] ; in 2015, Ou et al. [13] proposed to apply full convolution to semantic segmentation, which lays the foundation for full co...

In computer vision and image processing, edge detection concerns the localization of significant variations of the grey level image and the identification of the physical phenomena that originated them. This information is very useful for applications in 3D reconstruction, motion, recognition, image enhan...
The image dehazing problem consists in removing from images the degradations introduced by atmospheric phenomena like fog or haze, that scatter light and reduce the visibility of objects. From: Vision Models for High Dynamic Range and Wide Colour Gamut Imaging, 2020 ...
Fig. 1.The grayscale version of an image containing the face of a person. Subsequently, every pixel of the image is examined and compared to the surrounding pixels, as shown inFig. 2. This step aims to compare the darkness of the current pixel to the one right next to it, i.e., ...
Full size image Consider a tensor network [Math Processing Error]T=(G,A) consisting of a collection of tensors [Math Processing Error]A={a(v):v∈V} and an undirected graph G(E, V) defined by a set of edges E and a set of vertices V, that admits open edges22,35. The vertices...

1.2Classical techniques for retinal image analysis Many traditional techniques are used to analyze retinal images, which is important for detecting retinal diseases. In this regard, the steps consist of the detection, enhancement, measurement, and segmentation of retinal image features. To this end, ...
Advances in the scientific fields of photogrammetry and computer vision have led to the development of automated multi-image methods that solve the problem of 3D reconstruction. Simultaneously, 3D scanners have become a common source of data acquisition for 3D modeling of real objects/scenes/human bo...
