Image processing and implementation on fpga (spartan 3A video starter kit)

[EDIT: 20110524 10:47 CDT - merge duplicates, clarify - WDR]

hi

I am doing project on REAL TIME OBJECT DETECTION AND TRACKING AND IMPLEMENTATION ON FPGA (SPARTAN A VIDEO STARTER KIT) or DSP TIC6416. I have built a simulink model in matlab and converted in to fixed point model but when i want to convert simulink model in to verilog using HDL-coder i get this error for all blocks i have used in this model "matrices are not supported in this version" and an error for BLOB ANALYSIS block is "hdl-coder not support this conversion ". Please help me in this problem. I am using matlab 2010a.

I have a choice in implementation in fpga or dsp suggest me which one is easier from here. Please do reply

[Material from duplicate question #1]

I am using simulink blocks like from video source, rgb to intensity, binary conversion, gaussin filter, blobanalysis, draw rectangles, display video. so in simulink I have got the results to some extent but I want to convert model to hdl code. I don't know how can I convert such kind of model. Can I send you my model so that you can look it clearly and help me?

[Material from duplicate question #2]

Hi I am doing project of real time object detection and tracking and implementation in fpga (spartan 3A video starter kit) which has built-in camera and I can take output in monitor from fpga. But I have made a simulink model in matlab and I want to convert this model into verilog which i don't know. 1.how can I convert code using hdl-coder? 2. in matlab spartan 3A has its own blocks should I use these blocks for video in and out?

Video algorithms should use a pixel streaming algorithm in order to be converted to HDL. Consider how many bits even a small image contains when represented as a matrix signal: a 128x128 pixel 8-bit image frame contains 128k bits. Each bit requires a distinct wire or pin in hardware. To address your second issue, the Computer Vision System Toolbox has no blocks supported for HDL code generation. You can see the full set of blocks supported for HDL code generation with the 'hdllib' command.
