Moving object segmentation using Improved Running Gaussian Average Background Model (IRGABM) is proposed in this paper. Background subtraction for a relatively static background is a popular method for moving object segmentation in image sequences. However, there are some problems for the background subtraction method, such as the varying luminance effect, the background updating problem, and the...
Image registration method by using corner and edge contents is proposed. In this method, the algorithm runs as a coarse-to-fine strategy to find a precise alignment between images in a rigid planar motion. In a coarse stage, landmarks in both images are detected by Harris corner detection. Rough alignment is geometrically found by matching a group of corners, instead of one-on-one, across two images...
Semi-automatic segmentation of still images has vast and varied practical applications. Recently, an approach "GrabCut" has managed to successfully build upon earlier approaches based on colour and gradient information in order to address the problem of efficient extraction of a foreground object in a complex environment. In this paper, we extend the GrabCut algorithm further by applying...
Hyperspectral imagery generally contains enormous amounts of data due to hundreds of spectral bands. Band selection is often adopted firstly to reduce computational cost and accelerate knowledge discovery of subsequent classificationand analysis. Recently, a new clustering algorithm, named "affinity propagation," is proposed. Different from the popular k-centers clustering technique, affinity...
Size measurement of rocks is usually performed by manual sampling and sieving techniques. Automatic on-line analysis of rock size based on image analysis techniques would allow non-invasive, frequent and consistent measurement. In practical measurement systems based on image analysis techniques, the surface of rock piles will be sampled and therefore contain overlapping rock fragments. It is critical...
Segmentation of the chessboard grid is a crucial step in coordinate extraction for chess video annotation, content-based indexing of chess videos and for content analysis in prototyping vision systems such as a chess robot. This paper deals with the segmentation of grid elements from a populated chessboard taken at a lower angle view. The proposed approach couples the line-based grid detection method...
