Smoothing algorithm in Multi Pascal

To improve the visual quality of an image represented as two-dimensional aary of pixel values, a smoothing algorithm is sometimes applied. A simple smoothing algorithm is to replace the value of each pixel by the average of its immediate neighbors. Each pixel has 8 immediate neighbors, inclluding the diagonal neighbors. This algorithm replaces the value at each pixel by the average of 9 pixels, consisting of itself and the 8 neighbors.

So, how to write and run a parallel programming(simulate as it running on parallel processors) to apply the smmothing technique and to simplify shouldn't modify the pixels along the 4 outer boundaries of the image array.

what if you only do what you have to do to: (X1+1,Y1+1,X2-1,Y2-1)

Can you give me some information about "Multi-Pascal"?
This is the first time I'm hearing about it.

Mee too, it's the first time I hear about Multi-Pascal. Besides that, ¿why d'you say "parallel programming"?.

Smoothing process of an image can be achieved by using Bèzier's curves, even splines, algorithms to increase the number of point between two points of a given portion of a curve. That makes saw-tooth effect be diminished as much as you want.

If that is what you're looking for, I had the same problem some years ago, and I have developed the exact solution for that, using spline-curve. Just shout out.

you call it 'parallel programming' because your TP/BP program (even under DOS) may execute two tasks at same time. For example, remember those installation programs that copy a file and display two progress bars. bar 1 indicates the current prozents of the entire installation process and bar 2 shows, how many bytes of the current file are actually copied. Other programs scroll an info text across the screen while copyng files. i had units to make this in TP 6.0, but unfortunally, i dont have'em anymore. i can only suggest to see http://garbo.uwasa.fi
there is a big pascal (and other langs) library, i believe i found it there somewhere

Well; to show progress bars, you don't really need parallel processing at all...

omsecCommented:
well, that was just an example. "Pascal parallel Programming" means, your TP/BP - does actually execute more than one things at same time, it's kinda multi tasking under dos. Older programs also used this way to play some "beepy music" over the System's Speaker while the Program/CPU does other stuff

omsecCommented:
but i dont really get why you need multi pascal to load a picture. do you want to do something other while the file is loading from disk ?

I know what p.p. is, Omsec; my doubt regards only the fact WHY Satiya is needing it (BTW, who seems to be dissapeared... :(

Oh, God !!; ¿what's that matter of "4 outer boundaries"?
