Edit Please don't do this! You will find that MATLAB arrays either numeric or cell will let you do the same thing in a much faster, much more readable way.

In this FPGA Verilog projectsome simple processing operations are implemented in Verilog such as inversion, brightness control and threshold operations. The image processing operation is selected by a "parameter. The image writing part is also extremely useful for testing as well when you want to see the output image in BMP format.

In this project, I added some simple image processing code into the reading part to make an example of image processing, but you can easily remove it to get raw image data. All the related questions asked by students are answered at the bottom of this article.

First of all, Verilog cannot read images directly. Below is a Matlab example code to convert a bitmap image to a. The input image size is x and the image. After reading the image. Below is the Verilog code to the image reading and processing part: To change the processing operation, just switch the comment line.

After processing the image, it is needed to write the processed data to an output image for verifications. The following Verilog code is to write the processed image data to a bitmap image for verification: If there is no header data, the written image could not be correctly displayed.
