Hello Rizi,
I suppose you're new to digital design and FPGAs, is that correct? If yes, then the best option for you is to transfer the image using the serial port. This is quite slow – how large are your images?

Do you know this fellow? Are you both taking the same course?

Thanks for reply
i am working on real time visual tracking project.
i have setup image processing pipeline.
now i want to save small template (greyscale frame i.e 120x150 ) in ROM, and i want to recal
that template for comparison on each frame of video stream,during the process when
video streaming will be flowing through the FPGA board.
The video is flowing at 60 frames per sec and it is in NTSC 4:2:2 formate.
Thank you
Rizi

120x150 x 8bit pixels = 141Kbits (roughly). You could conceivably store this size reference frame in on-chip block RAM. Or you could store it in off-chip PROM, with some user logic for accessing the frame in PROM.
The video is flowing at 60 frames per sec and it is in NTSC 4:2:2 formate.
NTSC is a composite ~30FPS interlaced format. There is no such thing as "NTSC 4:2:2".
Let's try describing the video input again:
Do you have the time to spend learning FPGA design? Or do you want to focus your efforts to design the image processing algorithm and hire someone else to help with FPGA implementation?

Yeah, i have spent time to learn FPGA. but still not perfect.
Few of us are perfect, and the rest are liars. <== oops, this came out wrong
Most of us are not perfect, and the rest are liars. <=== this is what I meant to say
Sounds like fun!

hi
i m also doing d same project .i m processing a image store in pc .
can u plz tel me
1.which kit should i prefer for processing my image for its enhancement ,its pixel clearity
2. how to transfer a image from pc to that kit
3.i m applying nufft algorithm ????what actually it is.

sir, i want to implement edge detection using canny or adm edge detector and linking algo on xilinx using vhdl.
so please tell me which format of image is suitable for this algo and how i can load the image..

Jeez, people, do you even put one iota of thought into these homework problems?
How do you get the video data to the board? How do you get it out of the board? Do you have code to do whatever transformations are required?

im curious about image processing for my image work andi think the images processing in vhdl is alomst same as long as the language is same, and this is image processing code in c # in my image work, hope it can help. and you also can check this open source to see more detail. http://stackoverflow.com/

thank you for you image processing code, i believe it will work great. but for some VB developer. they may looking for VB image processor to do some image processing work and read image.

hi all,
i am going to do image processing in fpga.i want to know the coding for transferring the image from pc to fpga.so please help me.thanks in advance.

As pointed in this thread, please refer to http://forums.xilinx.com/t5/Virtex-Family-FPGAs/image-processing-in-virtex5/m-p/119158 for basic info.
Please open a new thread only if you have any specific query regarding Xilinx products and usage,
Thanks,

thanks for ur reply.i am not able to understand.so please help me for how to write the vhdl coding for tranfering the image in to fpga
