Affine-Gradient Based Local Binary Pattern Descriptor for Texture Classification
We present a novel Affine-Gradient based Local Binary Pattern (AGLBP) descriptor for texture classification. It is very hard to describe complicated texture using single type information, such as Local Binary Pattern (LBP), which just utilizes the sign information of the difference between pixel and its local neighbors. Our descriptor has three characteristics: 1) In order to make full use of t...
متن کاملRotated Local Binary Pattern (RLBP) - Rotation Invariant Texture Descriptor
In this paper we propose two novel rotation invariant local texture descriptors. They are based on Local Binary Pattern (LBP), which is one of the most effective and frequently used texture descriptor. Although LBP efficiently captures the local structure, it is not rotation invariant. In the proposed methods, a dominant direction is evaluated in a circular neighbourhood and the descriptor is c...
متن کاملFast Algorithms for Computing Binary Correlation
Cross-correlation is widely used to match images. Cross-correlation of windows where pixels have binary values is necessary when thresholded sign-of-laplacian images are matched. Nishihara proposed that the sign of the laplacian of an image be used as a characteristic, that is robust to illumination changes and noise, to match images. Thresholding the sign of the laplacian of an image results i...
متن کاملGlobal Binary Patterns: A Novel Shape Descriptor
In this paper, we propose a novel shape descriptor, called Global Binary Patterns (GBP), based on interpreting intensity values along a direction in an image as binary numbers, converting these binary numbers to their decimal values and concatenating these decimal values as the elements of a vector that is the GBP representation of the shape. Comparing with some widelyused state-of-the-art meth...
متن کاملA Study on the Use of a Binary Local Descriptor and Color Extensions of Local Descriptors for Video Concept Detection
In this work we deal with the problem of how different local descriptors can be extended, used and combined for improving the effectiveness of video concept detection. The main contributions of this work are: 1) We examine how effectively a binary local descriptor, namely ORB, which was originally proposed for similarity matching between local image patches, can be used in the task of video con...
