Image adaptation method based on edge vision protection

Abstract

The invention discloses an image adaptation method based on edge visual protection. The method comprises the following steps: S1, calculating an importance degree graph: calculating a weighted importance degree graph according to a gradient graph, a saliency degree graph and an edge line; S2, optimizing the energy diagram: taking the importance diagram as a basic energy diagram, and optimizing theenergy diagram by utilizing the visual characteristics of the inclination degree and the bending degree of the lines on the basis of the importance diagram; and S3, realizing line cutting adaptation:performing forward line cutting operation according to the optimized energy diagram to realize image adaptation. On the premise of ensuring the display effect of the significant object, the continuity and fluency of the edge and the contour are improved by keeping the shape of the edge contour of the non-significant area.

Description

technical field

[0001] The invention relates to an image adaptation method, in particular to an image adaptation method based on edge vision protection. Background technique

[0002] At present, with the rapid development of computer-aided diagnosis technology, a variety of medical imaging technologies have appeared clinically to obtain medical images of human internal tissues and organs, such as computed tomography (CT), nuclear magnetic resonance imaging (NMRI), medical ultrasound Imaging (UI), etc. However, the pixels of these medical images are fixed or set only once, causing the images to be displayed on different display devices (such as computer screens, projectors, laptops, tablets, smartphones, etc.) to be adjusted to accommodate different resolutions and display properties such as aspect ratio. The process of image adjustment is also called image redirection or image display adaptation. Traditional image adaptation methods mainly include uniform scaling and dire...
