hi

I want a code in VHDL for erosion of a image.
i have implemented this in matlab . i want in vhdl . so please help me.

I also want code for processing image
my boss want's it on monday next week
I only have 5 working days left
please help me
it is urgent
i am from india an never learned to think myself

------------

now seriously:

questions like these, mr. krish sharma, are nothing else then spam.
you are describing nothing than just a phrase "erosion" but no details 
about sources, destinations, format, boudary conditions or constraints

if you do not anticipate yourself, that a person you are asking for 
help, requires this information, than you can do nothing more in your 
engineers life than pressing a generate button in MATLAB's VHDL coder 
tool.

We have implemented a application which uses this erosion to count the 
number of coins in a image .
In a image of coins in which some will be overlapped so we use operation 
operator then we will count the number of coins in a image .
We got the output in matlab.
Now we have to this thing in VHDl i.e  we have write VHDL code for 
counting number of coins in a image using erosion operator.

Find the attached matlab code and eroded image.

Hi,

i guess you have to rewrite the functions mathlab use.
Maybe u can compress some of the algebraic functions and run them 
parallel.

Creating FPGA Code from a simple SW Definition is an issue. It cannot be 
done using a predefined method or process, but has to take individual 
options into account in terms of FPGA capabilities, certain demands of 
pipelining, accuracy and parallization.

The only thing you can do is to get informed about possible strategies, 
try to apply them to your individual task and realize parallelization in 
MATLAB to verify your thoughts. Transforming to VHDL code can be done 
automatically from the Coder, but the design structure will have to be 
designed in mind.

In VHDL there isn't an erosion operator. You have to understand what 
each Matlab function does. Then you have to rebuild this function in 
VHDL. First you have to decide, shall it be able to synthesize or not. 
If yes even an experienced developer will need some month from scratch, 
an unexperienced one year.

At least. And some will not finish it up forever...

That looks a little bit suspicious to me:

The very same post with 2 years in between?
I will lock the thread.
If anyone wants me to reopen it: send me a message with a valuable 
reason.
