Cloud-containing remote sensing image compression method based on filling strategy
A remote sensing image and compression method technology, applied in the field of image processing, can solve the problems of not considering the edge information of the filled area, high coding consumption of invalid areas, high coding consumption of high-frequency information, etc., and achieve peak signal-to-noise ratio (PSNR) index improvement and reduction. Coding consumption, reducing the effect of high frequency wavelet coefficients

Embodiment Construction
[0035] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0036] refer to figure 1 , the specific implementation steps of the present invention are as follows:
[0037] Step 1: Extend the boundaries of cloud-containing remote sensing images and cloud mask images.
[0038] 1.1) Input the cloud-containing remote sensing image I and the corresponding cloud mask image M, where I is a grayscale image and the bit depth is B N ; M is a binary image, the region of interest is represented by 0, and the cloud region is represented by 1, and the two images have the same size;
[0039] 1.2) Boundary extension of cloudy remote sensing images:
[0040] If W is an odd number and H is an even number, add a column of data to the far right of the original cloud-containing remote sensing image, and the added data is the Wth column data of the original cloud-containing remote sensing image;
[0041] If W is an even numb...
