FPGA based OV7670 – Further image compression
In my last post, I was talking about image compression methods, mainly DCT transform based along with colour transform based. I’ve now combined these together and have managed to break […]
FPGA based OV7670 – Image compression/processing
Image compression is a massive topic and to be honest, a bit of a buzzword title. Images can be compressed in multiple ways. One of the simplest being reducing the […]
FPGA based OV7670 – Affine Image Transformations
As of yesterday, I’ve got a new laptop (woop woop I7-7700HQ)! Obviously that meant transferring data over though a bit of WiFi and an overnight transfer deemed me ready to […]
FPGA based OV7670 – Image segmentation
As I mentioned in my last post, I wanted to try some image segmentation! I had a quick go at histogram based segmentation where the largest peak of the histogram […]
FPGA based OV7670 – Edge Detection
One of the staples of image processing is edge detection. Edge detection is generally one of the primary steps for further image processing methods including feature detection. Conceptually, edge detection […]
FPGA + OV7670 = Super slow UART webcam
What do you get when you combine an FPGA with some SDRAM and an OV7670 camera, transferring uncompressed frames through UART? Really poor performance, reliability and a pretty useless end […]
