Digital negative and Contrast stretching in Matlab

[@commonengineeering4794]

very good explanation

[@AhsanZafar]

can you tell how to do gray level stretching with clipping?

[@pratikian]

What do you acctually mean by clipping ?

[@srinivassai7926]

hi... can you explain about contrast stretching when r1=rmin,s1=0,r2=rmax,s2=255 ???

[@pratikian]

So intutively its like any input pixel value less than rmin will become zero and any input value above rmax will become 255
And the values between rmin and rmax will be in streched in the range of 0 to 255.
