i would liek to find the peaks in a 3d plot, please find the 3d plot of an images, i want to calculate all the local minimas( valleys) of the given 3d plot

Answer 1

[Image Analyst]

Try imregionalmin and imregionalmax.

i cant visualize or tailor the output with that,

[AADITYA DARAKH]

i need to extract these points, or the column with the most valleys. i am not able to get a good ans with imregionalmax/min

is these any way i cant visualize the output?

using find peaks?

Why not? You forgot to post your code. Also, attach your 2-D image array.

[AADITYA DARAKH]

o=17;

C=imread("cameraman.tif");

h=fspecial("motion",15,o);

z=imfilter(C,h);

C=fft2(z);

C=fftshift(C);

C=abs(log(1+C));

R=radon(C);

surf(R)

imshow(R,[])

impixelinfo()

N=length(R);

N=ceil(N/2);

for j =10:170

B(1,j)=R(N,j-9)+R(N,j-8)+R(N,j-7)+R(N,j-6)+R(N,j-4)+R(N,j-5)+R(N,j-4)+R(N,j-3)+R(N,j-2)+R(N,j-1)+R(N,j)+R(N,j+1)+R(N,j+2)+R(N,j+3)+R(N,j+4)+R(N,j+5)+R(N,j+6)+R(N,j+7)+R(N,j+8)+R(N,j+9);

end

[m,n]=max(B)

am i able to understand my problem to you? or i need to make it more clear?

[AADITYA DARAKH]

the image matrix is RADON TRANSFORM of the log shifted FFT transform of the image
