To get the liver image segmentation from the whole abdominal medical image lays the foundation of liver three-dimensional reconstruction system, in that a good image segmentation result really makes a big difference in the three-dimensional reconstruction. This paper focuses on the research into Graph Cuts image segmentation algorithm, especially its energy function. Improved Gaussian distribution...
In ITS (intelligent transportation system), on-road object detection algorithm is one of the most important research fields and obstacle segmentation is a key factor in obstacle detection approaches. In this paper, a simple and fast segmentation approach is proposed for on-road object in ITS. Firstly, a simple method is applied to detect the interest pixels in the transportation scene images by the...
Among several contour splitting algorithms drop-fall algorithm is convenient and accurate for separating handwritten numerals. A set of drop-fall algorithms can produce four possible cutting paths. Based on four drop-fall algorithms, this paper deals with a pattern-oriented strategy for segmenting touching digits in order to solve the problem of determining which drop-fall algorithm producing the...
In experiments of soil mechanics, it is important to study the motion of sand grains at high pressures. Technologies of image segmentation and object tracking can help to resolve this problem. Aiming at the dense sand grains images, this paper proposes a method to track sand grains from image sequences. A novel approach of dense grain segmentation based on boundary exploration is proposed. Firstly,...
In this paper, we present a novel approach which employs the temporal redundancy of video texts to improve the performance of text segmentation and stroke extraction from complex background. We first demonstrate how to obtain the required aligned text image sequences from video frames via a robust corners-set matching scheme. Then the changing background pixels can be identified and removed by exploiting...
