Embodiment Construction

[0055] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0056] An image seamless fusion method based on consistent optimization of color and transparency of the present invention establishes a unified mathematical model to calculate the fusion label and transparency of the foreground and background images in the overlapping area, and solves it through a two-step optimization strategy: First, in the color channel, the fusion labels of the foreground and background images in the overlapping area are calculated based on the graph cut energy optimization algorithm, and then in the transparency channel, the transparency is solved according to the energy function that conforms to the gradient difference distribution of the foreground and background, and fusion is performed based on the transparency.

[0057] Include the following steps:

[0058] 1) Calc...

Abstract

The invention discloses a seamless image fusion method based on consistent optimization of color and transparency and belongs to the field of image graphic processing. According to the adopted technical scheme, firstly, fusion labels of foreground and background images in an overlapped area are calculated in a color channel based on a graph-cut energy optimization algorithm; secondly, energy functions conforming to foreground and background gradient difference distribution are constructed in a transparency channel so as to solve the transparency; finally, seamless image fusion is performed based on the transparency. By means of the seamless image fusion method, better division effect can be obtained, accordingly the transparency distribution of the foreground and background images in the overlapped area is influenced, and the transparency values of the foreground and background images can be more even. Compared with other fusion methods, the seamless image fusion method can have better fusion effect.

Description

technical field [0001] The invention belongs to the field of image and graphic processing, in particular to an image seamless fusion method based on consistent optimization of color and transparency. Background technique [0002] Image fusion refers to combining two or more images into a new image. Image fusion plays an important role in virtual reality, digital media, and style design. Image fusion techniques can be divided into three levels: pixel-level fusion, feature-level fusion, and decision-level fusion. Pixel-level image fusion is mainly the comprehensive processing of information directly on each source image data, and it is the most basic tool in image fusion. As an important application of pixel-level image fusion, seamless image fusion technology plays a core role in the field of image and video editing. [0003] At present, there have been a large number of researches on image seamless fusion methods, mainly in two categories: one is the fusion method based o...
