Problems solved by technology

However, when the geometric model is used to cartoonize the target area, accurate geometric features need to be extracted, which leads to a large amount of calculation and high quality requirements for the photos
In addition, since the reference overall structure of the shape of the target area is defined in advance, for the actually captured photos, the geometric features of the target area may not be unified into one of the reference overall structures of the target area due to different shooting conditions. In the framework, for example: the reference overall structure of the front face is defined in advance, but in actual shooting, only the side of the face may be captured, so only one eye of the person is shown in the photo, and the actual extracted geometric features cannot correspond to In the reference overall structure of the front face defined in advance, it cannot be cartoonized
Another example is that during the shooting process, if the light is too strong, people will squint their eyes. At this time, the round eyes will become oval eyes. The oval eyes cannot correspond to the reference overall structure of the pre-defined face area, resulting in the failure of cartoonization.
For another example, when the eyes are closed, the eyes will be blocked by the eyelids, so that the eyes cannot be extracted, and the face cannot be cartoonized according to the reference overall structure of the face area.
Therefore, the adaptability of the geometric model method is poor

Abstract

A terminal and an image processing method and device. The image processing method includes: acquiring a consistent texture area based on channel parameters of the first image; determining an edge area in the first image; filling the consistent texture area; filling the edge area to separate the consistent texture area. The technical scheme of the invention has simple and strong adaptability to the image special effect processing process, and the calculation amount is small and the speed is fast.

Description

Technical field [0001] The present invention relates to the technical field of image processing, in particular to a terminal and an image processing method and device. Background technique [0002] With the development of digital media technology, special effects processing of images has received extensive attention and research. Take the cartoonization of videos or images as an example, which is also called Imagestylization or Image Abstraction. It belongs to the research field of Non-photorealistic rendering. Compared with Realistic rendering, NPR is more Focus on the personality of the image. Cartoonized images are used in many fields, such as: video conferencing, online games, etc. In addition, using virtual cartoon avatars instead of real faces, on the one hand, can increase the data transmission speed of the network, on the other hand, it also creates a relaxed and harmonious atmosphere. [0003] At present, there are two methods for acquiring cartoon images: training lear...
