Please refer to the previous articles part 1, part 2, part 3, part 4, part 5 in this series. The following function is used to process the same input image twice. So two independent header files were created from the same image in this case as cup.h and cup2.h and used the following image processing difference process,

void test_images_diff(uint8_t *image_input1, uint8_t *image_input2, uint8_t *image_output, Image_processing *img_proc){
   img_proc->send_params(image_width, image_height);
   img_proc->send_image(image_input1); //in input buffer

   img_proc->switch_buffers();

   img_proc->send_image(image_input2);
   img_proc->switch_buffers();

   img_proc->send_binary_sub(true, true);
   img_proc->wait_end_busy();

   img_proc->switch_buffers();
   img_proc->read_image(image_output);
}

This image processing demo takes these two identical images and performs the difference between both with the following output,

As expected, the output image (cancellation) is as follows,

In the next article we will be describing more image processing demos in this platform as well as more details, stay tuned. The Lattice ICE40 FPGA UltraPlus Breakout Board is an excellent, low cost, but powerful enough to even tackle image processing applications and is available at DigiKey.

Have a wonderful day!
