Image composition is a very important technique in computer generated imagery (CGI). Besides some factors such as contrast, texture, noise that affect the quality of the composition, color harmony between fore- and background is also an important issue that should be carefully dealt with. However, in the previous image composition techniques, the color harmony between fore- and background is seldom...
This paper presents a robust and accurate self-calibration approach from unordered wide-baseline images. An optimization model based on affine transformation is introduced into propagation to acquire higher accuracy of quasi-dense correspondences. Our self-calibration algorithm is completed through two-layer iteration. In the inner layer, global objective function and local photometric consistency...
