pik33 asked What is in the picture? It looks like wavelet compressed something: )
In a 256 x 256 image of lena has 3 sub bands. RGB. The first step of JPEG 2000 is to perform DWT The picture is 3 levels of lifting step on the red sub band.
1 level reduces the image to 128 X 128 at the same quality if you include the other pixels. The 2nd level reduces to 64 X 64 and the 3rd level is 32 X 32 in the
lower right hand corner. The next step would be EBCOT (Embedded Block Coding with Optimized Truncation). https://github.com/develone/Ultibo_Proj ... r/jpeg2000
is the complete openjpeg. This work is just learning FPGA in hopes of combining with Ultibo. https://github.com/develone/Ultibo_Proj ... er/progcat.
The RPi3B+ is complete Development tool in the palm of your hand. The combination of the FPGA with Ultibo provides the logic level to control any number of devices.
Let me if you have any questions
