Hi, Since the DE2 board has RS232 and Ethernet, you can use either of these to interface with the PC.
Using RS232, from PC you can send / receive data with the help of hyperterm.
For using Ethernet, i think you have to use Embedded OS if your board supports this.
Now if you are looking for the fpga to load the images from Hard disk directly, then y

From my point,
you can write the hdl by yourself by reference matlab function.
Since the filter is 2D, you need line buffer to save some lines of image to perform the filter operation if the image data is raster-scan order.
On the other hand, you have frame buffer to save
whole image data, you can write an small controller to (...)

Both methods work fine. The difference is mainly the direction of CCLK.
