Description: We de¯ ne
a predicate for measuring the evidence for a boundary between two regions using a
graph-based representation of the image. We then develop an e±cient segmentation
algorithm based on this predicate, and show that although this algorithm makes greedy
decisions it produces segmentations that satisfy global properties. We apply the algorithm
to image segmentation using two di® erent kinds of local neighborhoods in
constructing the graph, and illustrate the results with both real and synthetic images.
The algorithm runs in time nearly linear in the number of graph edges and is also fast
in practice. An important characteristic of the method is its ability to preserve detail
in low-variability image regions while ignoring detail in high-variability regions.-C++ implementation of the image segmentation algorithm Platform: |

Description: 一个简单的银行的计算系统 适合初学者看看 对了 是C#程序哦 -Abstract：As a region merge technology for image segmentation, traditional method of Region Adjacency Graph（RAG）has lots of
shortness such as complicated data structure and algorithm, difficulty of expansibility and maintenance, limits on available feature factors
and great amount of memory waste. Therefore, a new approach is proposed which provides a new framework for region merge
using object-oriented technique. In this frame work, the dissimilarity index, properties, adjacency and actions of regions can be defined,
extended and merge process is fully simplified Platform: |

Description: In the proposed algorithm, these two issues are solved by a novel predicate, which is defined by the sequential probability ratio test (SPRT) and the minimal cost criterion. Starting from an over-segmented image, neighboring regions are progressively merged if there is an evidence for merging according to this predicate. We show that the merging order follows the principle of dynamic programming. This formulates image segmentation as an inference problem, where the final segmentation is established based on the observed image. We also prove that the produced segmentation satisfies certain global properties. In addition, a faster algorithm is developed to accelerate the region merging process, which maintains a nearest neighbor graph (NNG) in each iteration. Platform: |
