Over the past two weeks, I have finished the desired image filters (chroma-key, contrast, and brightness). I wrote a chroma-key implementation in SystemVerilog that takes in two 16-bit pixel values and a threshold determiner and outputs either the original 16-bit pixel value or zero depending on whether the provided pixel value is sufficiently close to the provided “background” pixel value. This implementation also uses Quartus’ synthesized nine-bit multiplier modules on each “color” in the 565 pixel values. The specified background color and threshold values also allow the chroma-keying module to work with the FPGA hardware switches such that the removed color and the sensitivity of the chroma-key filter can be set dynamically after hardware configuration. I have also finished contrast and brightness modules, although that would be tested at a later date (when the entire studio is integrated with all four cameras and the FPGA). It is likely that the contrast module would require using decimal multipliers on the FPGA.<\/p>\n
As Breyden has the FPGA and cameras in his possession, he very kindly tested and debugged my code (which had an LSB and MSB mix-up error) and improved the threshold handling to be more sensitive across the desired background ranges. The effect of our image filtering modules can be seen in his status report this week.<\/p>\n
I am on track with the schedule as all image filters are more or less finished. Over the next week, I will work on the final presentation and the final report as we finish up our project. I may also help Breyden with the integration process and\/or the testing process depending on logistical details.<\/p>\n","protected":false},"excerpt":{"rendered":"
