[chitra ranganath]

hi,
i`ve an image, and i need to store the pixel values into a text fille, pls tell me how will i do this

 

[ckshivaram]

first open the image using let o=imread('image location\name.jpg')......
then assign this value to other variable using p=i;
and store this as a m file with a name eg. image.m
again if u want to use this data simply write - load image

thank u for the reply. but if i want to use this in xilinx it must be as text rite. so should i save as word pad??? or continue with .m itself.
thanks in advance

.m file should be enough for that purpose, unless you have any special requirements to be done.....

sir its taking too much of time to store pixel values. before this i tried on cameraman image it happened quickly but for mri image its taking long time is there any other solution

MRI resolution of picture is complex compared to other normal pictures... definetely it would take more time..

try with a simple picture first......
