Designed for Computer Vision

Vision has long been recognised as the most 
powerful sensing modality. Computer vision is 
all about extracting meaningful information 
from the abundance of data provided by video 
cameras.  The sheer amount of raw data 
presents challenges: processing the data is 
difficult and it is non-trivial just to transfer 
the data to a computer.

The FastVis FPGA camera addresses 
technological challenges in computer vision 
by combining a powerful FPGA directly with 
a 2 megapixel camera.  


The FastVis camera can be used for all types 
of computer vision algorithms.  E.g.
  * edge, feature detection
  * optical flow
  * object tracking & control
  * image and video filtering
  * downsampling
  * upsampling

FastXForm
FastXForm is an online service that provides 
translation from a subset of C to a bitstream that 
will run on the FastVis camera.
* Enables rapid development. Develop and debug 
    on standard PC using FastVis host library
* Easy to use, well known language.
    C is much easier than Verilog/VHDL.
* FastXForm takes care of scheduling and pipelining
* Integrated with device drivers which means you 
    can focus on the computer vision algorithm
* Modules written as a per-pixel function call
* fv_get_pix function allows access to pixels
    offset by row, column and even frame
* Optimises constant multiplication, provides
   square-root and division
* Low cost

Example of 5x5 Gaussian Blur:

uint16_t gaussian_kernel[5] = {
  1,  4,  6,  4, 1
};
void gaussian_5x5_x(fv_stream_t *stream) {
  uint64_t ret = 0;
  int i;
  for (i = -2; i < 3; i++) 
    ret += gaussian_kernel[i] * 
             fv_get_pix(stream, i, 0, 0);
  fv_put_pix(ret / 16);
}
void gaussian_5x5_y(fv_stream_t *stream) {
  uint64_t ret = 0;
  int i;
  for (i = -2; i < 3; i++) 
    ret += gaussian_kernel[i] * 
             fv_get_pix(stream, 0, i, 0);
  fv_put_pix(ret / 16);
}
