Now what IS the problem?<br />
A picture is grayscale if for all pixels the R, G and B values are the same.<br />
Making a colored picture grayscale is calculating the brightness of the pixel. A formula which i do not know.

That is for each pixel R, G and B value of this pixel has to be the same.

That is for each pixel R, G and B value of this pixel has to be the same.

<div>
to convert from color to greyscale:<br />
<br />
brightness = (R + G + B) / 3<br />
<br />
set R, G, and B to the value in brightness<br />
<br />

</div>


to convert from color to greyscale:

brightness = (R + G + B) / 3

set R, G, and B to the value in brightness

Thanks edey for that HSV formula. &nbsp;I used it and did notice an improvement.

hi .. everyone ...<br />
i have a problem here about the algorithm <br />
for classifiying an image into grayscale <br />
image and not. And if there is Delphi <br />
source code please tell me ok ...<br />
