Hello Everyone,
I have some issue when I'm trying to crop an image.
I have chosen a RGB Image(256×256) and converted it into grayscale image, then I check out the image pixel values. I have attached here only 8×8 dimension pixel values (shown in fig.1)
from the entire 256×256 pixel workspace values.
But when I crop that image using imcrop() command, then I get also that 8×8 pixel but with different values (shown in fig.2).
This creates the problem I get the different pixel values from same image when trying to crop that image with a specified dimension and also get differnt pixel values when stored it into a hex file for furthur processing.
Below is my Matlab code:
a =imread('cameraman.tif');a1=rgb2gray(a);rect=[1 7 7 7];i_c = imcrop(a1,rect);pixel = cell(8,8);ctr = 1;ctc = 1;for R=1:8 for C=1:8 pixel{ctr,ctc}=dec2hex(i_c(R,C)); ctc = ctc+1; end ctr = ctr+1; ctc=1;endfid = fopen('cam_data_tif_8.hex', 'wt');fprintf(fid, '%x\n', i_c);disp('Text file write done');disp(' ');fclose(fid);celldisp(pixel)disp ([pixel{:}]);
Please reply to me.Thank you.
