Problems solved by technology

[0009] The multi-operation adaptation method is to comprehensively use line clipping, uniform scaling, uniform clipping and other methods to achieve relatively good results when a single method fails in a specific order and quantity. The efficiency is low and the effect cannot be fundamentally enhanced

Embodiment Construction

[0088] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0089] refer to figure 1 ,like figure 1 As shown, an image adaptation method based on edge vision protection, including the following steps:

[0090] S1, calculate the importance map: calculate the weighted importance map according to the gradient map, saliency map, and edge lines;

[0091] S2, optimize the energy map: take the importance map as the basic energy map, on this basis, use the visual characteristics of the inclination and curvature of the line to optimize the energy map;

[0092] S3, line clipping and adaptation: according to the optimized energy map, perform forward line clipping o...

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...
