Mobile terminal for achieving high-quality real-time facial beautification

Abstract

The invention discloses a mobile terminal for achieving high-quality real-time facial beautification.The mobile terminal comprises an image input module, an image output module, a memorizer and a CPU connected with the image input module, the image output module, a transmitting module, a receiving module and the memorizer respectively, wherein a group of program codes are memorized in the memorizer, the CPU is used for calling the program codes memorized in the memorizer to execute the following operations of obtaining videos input by the image input module, extracting the videos frame by frame and using the videos as picture sequences, accelerating pixel-by-pixel independently-executed whole image beautification, image enhancement processing and shading processing of the skin zones of generated images through CPU hardware, conducting pixel-by-pixel fusion on the wholly whitened images and the wholly denoised images respectively according to the obtained shaded skin zones, and outputting the images through the image output module.The mobile terminal processes multiple sub-modules of a system in virtue of the hardware acceleration characteristics of the CPU, and the problem of low efficiency during CPU usage can be solved.

Description

technical field [0001] The invention relates to a mobile terminal for obtaining high-quality and real-time beautification. Background technique [0002] The beauty method usually consists of multiple basic steps, including the removal of noise such as external light and human skin in the image, human skin detection, face detection, freckle removal, skin whitening, image fusion, etc. [0003] As the most basic and important part of image denoising, it plays a vital role in subsequent algorithm processing. At present, there are many denoising algorithms, usually including Gaussian smoothing, bilinear filter smoothing, average filter smoothing, and block-based smoothing. Algorithms such as matching 3D denoising, in which the performance and effect of each algorithm have different degrees of difference, and each has different degrees of limitations, which has a greater impact on the selection of algorithms for application scenarios. For example, the average filter smoothing eff...
