An image adaptation method based on edge vision protection

Abstract

The invention discloses an image adaptation method based on edge visual protection, comprising the following steps: S1, calculating an importance map: calculating a weighted importance map according to a gradient map, a saliency map and edge lines; S2, optimizing an energy map: The importance map is used as the basic energy map. On this basis, the energy map is optimized by using the visual characteristics of the inclination and bending of the line; S3, line cutting adaptation: According to the optimized energy map, the forward line cutting operation is performed to achieve Image adaptation. On the premise of ensuring the display effect of the salient object, the present invention improves the continuity and smoothness of the edge and the outline by maintaining the shape of the edge outline of the non-salient 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 emerged in clinic to obtain medical images of internal tissues and organs of the human body, such as computed tomography (CT), 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.) and need to be adjusted to suit different resolutions and display properties such as aspect ratio. The process of image adjustment is also known as image retargeting or image display adaptation. The traditional image adaptation methods mainly include uniform scalin...
