wat wrong of my code (image processing)
hi guys, i doing the image processing for my project..& week after next is my submission date..so, i really suffer, stress & tension...coz if i can't finish i will fail my project...hope some1 can & will help me thanks a lot...some i using OpenCV library to code,some is in C/C++ language...i stuck in thinning module which is thin the ridge in onepixel thick...it contains 2 step, & this 2 steps got 4 conditions..if match the conditions, remove the contour point which is delete the pixel...in thinning it got 3*3 mask as below:
p9 p2 p3
p8 p1 p4
p7 p6 p5
1st step:
condition 1:
2<N(P1)<6
where N(P1) = p2+p3+p4+p5+p6+p7+p8+p9
condition 2:
T(P1) = 1
where T(P1) is transition 0 to 1 in order sequence p2, p3, p4...p9
condition 3:
p2, p4, p6 = 0,which mean this 3 position at least 1 is in 0, which is black color.
condition 4:
p4, p6, p8 = 0, which mean this 3 position at least 1 is in 0, which is black color.
if all the condition is match then delete the pixel.
step 2:
condition 1:
2<N(P1)<6
where N(P1) = p2+p3+p4+p5+p6+p7+p8+p9
condition 2:
T(P1) = 1
where T(P1) is transition 0 to 1 in order sequence p2, p3, p4...p9
condition 3:
p2, p4, p8 = 0,which mean this 3 position at least 1 is in 0, which is black color.
condition 4:
p2, p6, p8 = 0,which mean this 3 position at least 1 is in 0, which is black color.
if all the condition is match then delete the pixel.
so how to do it...i really dunno how..i used 1 month to fix it, but till now also not success...i really really hope got some1 will help me fix it...below is my code...hope correct for me...thanks...

}
cvvShowImage("Image Processing",thinimg2);
cvReleaseImage(&thinimg2);
thanks a lot....hear from u soon.......
