Abstract

The invention relates to the technical field of image processing, The invention discloses a method for realizing vehicle-mounted GUI skin removing by using shader, which comprises the following steps:a shader shader is programmed by using Opengl shading language GLSL, so that one shader shader runs on GPU in parallel to realize GUI color skin removing; Create two shaders in Opengl ES: Vertex shaders and fragment shaders, The invention adopts GPU to process data, realizes the skin real-time skin removing effect of any color of any figure based on Opengl ES, improves the speed of real-time drawing image for all pixels, vertices, texture position, hue, saturation, lightness and contrast, greatly improves the conversion efficiency, and achieves the requirement of small input and small modification.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for implementing vehicle-mounted GUI skinning by using a shader. Background technique [0002] In addition to the continuous improvement of the performance of the central processing unit (CPU), most of the existing vehicle-mounted central control equipment is also equipped with a professional graphics processing unit (GPU). Graphics processing unit (GPU) compared with central processing unit (CPU): CPU needs strong versatility to handle various data types, and at the same time has logical judgments, which will introduce a large number of branch jumps and interrupt processing , These all make the internal structure of the CPU extremely complicated. The GPU is faced with a highly unified type, large-scale data independent of each other, and a pure computing environment that does not need to be interrupted. [0003] Currently on the market, there is a new demand ...
