Embodiment Construction
[0064] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0065] like Figure 4 Shown is the work flowchart of a kind of image compression method of the present invention, comprises:
[0066] Step S401, prepare an initial grid whose size is [0, X]×[0, Y] and contains N grid nodes, and set the color value of the pixel whose coordinates are (l, h) in the image whose size is L×H Stored in the grid at coordinates (x i the y i ) of the nth i grid nodes, where:
[0067] is the rounding symbol;
[0068] Step S402, generating an optimized adaptive anisotropic grid through adaptive anisotropic grid technology;
[0069] Step S403, restore the original image by spline linear interpolation, check whether the image pixel information stored in the optimized adaptive anisotropic grid meets the requirements, if not, use the optimized adaptive anisotropic grid grid as the new initial grid, and re...
