Embodiment Construction
[0080] The present invention will be further described in detail below in combination with specific embodiments.
[0081] Image magnification is an image processing technology that obtains a high-resolution version of a low-resolution image through certain processing. Its core is how to supplement the gray value of the required pixels, that is, how to realize the supplement of image data. . Image magnification technology is widely used in the fields of public security, monitoring and remote sensing. At present, an image enlargement method based on a partial differential equation (PDE for short) is an important direction of research and development in the field of image enlargement. Applying PDE to image processing involves a very important issue, that is, the selection of equation parameters. The parameters of the equation include two types, one is the internal parameters of the equation, such as diffusion coefficient and fidelity coefficient. The other is the parameters us...
