This document discusses using MATLAB and a DSP processor for image processing and computer vision applications. It describes how MATLAB can be used to acquire images, analyze image content, and control actuators. However, image processing requires significant computational resources, so the code is run on a computer connected to a webcam rather than a microcontroller. The Texas Instruments TMS320C6713 DSK platform allows MATLAB codes to be implemented on a DSP processor for these types of applications. Example applications mentioned include medical imaging, object recognition, and robotic vision.

A vision based project has an image acquisition
device like a webcam as its eyes. Then we need a
processor that can make sense out of those captured
images and actuators.
One key point to note is that Image Processing has
huge computational requirements, and it is not
possible to run an image processing code directly on
a small microcontroller.
Hence, for our purpose, the simplest approach would
be to run the code on a computer, which has a
webcam connected to it to take the images, and the
robot is controlled by the computer via serial or
parallel port. The code is written in a software that
provides the tools for acquiring images, analyzing the
content in the images and deriving conclusions.
MATLAB is one of the many such software available
which provide the platform for performing these
tasks.

7.  CCS is TI’s proprietary IDE that provides a transition
between a high-level DSP program and an on-board
machine language program. It is used to:
 Generate programs for the C6713 DSP using C language,
 Load them into the DSK,
 Run them,
 Monitor program execution.

simulators and compilers
2.DSP boards for software development and testing before
target DSP hardware is available
3.Hardware testing tool such as emulator and logic analyzers.
4.Development assistance such as application libraries , real
time debugging hardware available

10. The Texas Instruments C6713 DSK platform, which can be
programmed using SIMULINK.
This gives us added advantage of easily writing codes on
MATLAB and implementing it on the DSP processors.
Based on a very-long-instruction-word (VLIW) architecture,
the C6x is considered to be TI’s most powerful processor.
