Sobel Filter for edge detection

Semester Project on FPGA - Verilog implementation on Sobel Filter for Edge detection on icoboard FPGA

The project folder src/ contains the following folders blink_example elementwise_matrix_mul sobel_flter

Make

Use make v_fname=<filename> to compile and upload binary file to icoboard.

contents

src/sobel_filter/ containts the following codes

image_initialization.py : read image and initialize it in sobel_uart.v conv.v : verlog code for convolution of 28x28(5 bit) image with 3x3(3 bit signed) filter. Gives the out put 26x26(8 bit) image sobel_uart.v : uses the conv module to apply the horizontal/vertical mask to the image and sends the output to PI using UART protocol. Since Icoboard is connected to Pi using GPIO pins, we are sending the data back using FTDI.
