I have one doubt regarding dsPIC that wheather it is possible to do image processing with dsPIC. Means if i provide image to dsPIC then will it do image processing task???

means operation normally we do on image like black and white high color temperature. and in of the case on white plane if dots are there then calculating theses dots. Likewise operation are possible??

is it memory problem or processing???
Means if i interface SD card interface with this then will it work??

Since you can only hold a part of the file in the memory, you will have to stream the file in and out and process it part-by-part. SD card is slow to write and cannot stand too many write cycles.

You certaintly can perform nearly any operation, but it probably will take much longer than you expect.

Is it possible with Resp-PI or Beagle bone black???

How big is your image? Monochrome or colour?
What kind of image processing?
How fast do you want the processing?

I would look at STM32F429 DISCOVERY. Comes with 2MB flash, 256KB RAM, 8MB external RAM, TFT LCD, camera interface.

i want to do process on image like changing color temperature, Counting lines and processes done using matlab.
Image will be colored.
it should be take time as time taken by Computer. Little bit slow can be OK.
STM32F429 DISCOVERY is ARM??

You have to start putting some numbers to your request.
What is the size of your image?
How slow is your computer?
How long does it take your MATLAB program to process the data?
What would be an acceptable processing time?

Yes, STM32 is ARM.

the size of image is 1680x1050.
My pc have i3 processor. So it does it in near about in 1 second.
matlab also take 2-3 sec.
Acceptable processing time s upto 40 sec.
