Image Processing

The image processing program is written in python with uses of libraries like numpy, matplotlib.
The technique of compressing images is to decompose a black-and-white image into its Singular Value Decomposition form. Each singular value corresponds to a layer of details of the image. The bottom layers contain the general frame, which looks like large grids, whereas the top layers contain the details, which looks like splatter or dots.
To compress the image, limited layers are selected and compose together such that limited level of details is kept.
What to Expect
As mentioned above, the several bottom layers of the SVD of an image contained frames that were too general. They were just large grids without any details.
I wish to investigate image processing techniques that recognize the layers containing the most important information of the image. With these mechanisms, we can save more storage space by maintaining the minimum number of layers within an image, without losing the essence of the information in that image.
