Abstract

A salient object detection method based on histogram power function fitting comprises the four steps of the histogram power function fitting, a superpixel classification, a salient region problem and salient object detection. The salient object detection method based on the histogram power function fitting has the advantages that gray threshold is obtained through using an FT saliency map, a figure manifold sorting method, an SLIC method superpixel classification and the histogram power function fitting, under the situations of multiple images, multiple targets and complex scenes, the detection efficiency is high, the performance is good, the precision is good, the problem in salient object detection fields is solved, by means of the salient object detection method based on the histogram power function fitting, the execution speed is high, and the complexity of algorithm is low; meanwhile, higher detection precision can be guaranteed.

Description

technical field [0001] The invention relates to the field of image salient target detection, in particular to a salient target detection method based on histogram power function fitting. Background technique [0002] As we all know, the rapid development of computer performance and functions provides reliable and feasible conditions for machine intelligence. With the deepening of disciplines such as machine learning and pattern recognition, people increasingly hope that computers can complete tasks more autonomously and intelligently. To achieve this goal, the computer needs to be able to understand the surrounding environment. The main way for humans to perceive external information is through vision, so the key to a computer's understanding of the surrounding environment is the ability to process visual perception. [0003] The salient target is the target that people pay the most attention to in the image, and generally contains more interesting and useful information. ...
