Multi-feature fusion underwater target modeling and optimization method

Abstract

The invention discloses a multi-feature fusion underwater target modeling and optimization method, which locates the target area by performing similarity modeling on the corner points of underwater image generation, and derives the discrimination basis for underwater target information extraction; The texture and contrast features inside the image select the label that accurately represents the target information in this area, and use the ERM to propagate the label to obtain the initial target image; and combine the image space, texture and color features to optimize the propagation results to solve the initial target image. The problem of uneven grayscale changes. Compared with the traditional underwater target modeling and optimization method, the method of the invention integrates various target features, improves the accuracy of underwater target modeling and improves the overall performance on the premise of ensuring the good operation speed of the algorithm.

Description

technical field [0001] The invention belongs to the technical field of target modeling, and relates to a multi-feature fusion underwater target modeling and optimization method. Background technique [0002] Object modeling technology plays an important role in underwater scientific research and practical engineering. However, under the influence of underwater target diversity, scene complexity and imaging ambiguity, underwater imaging usually faces problems such as complex lighting conditions, low target contrast, and turbid water, which brings great challenges to graph-based underwater target modeling. more difficult. Graph-based target modeling has been widely studied due to its fast and accurate advantages, but this model relies heavily on the selected prior propagation labels, and the complex underwater environment will distort the feature difference between the background and the target, resulting in If the labels representing the target features are not selected acc...
