how to do binary conversion of an image?

[James Tursa]

Please provide an example of what exactly you are trying to do.

[Image Analyst]

Image segmentation, for example by thresholding, is one way. Please read this and then attach your image and show what you expect as an output.

read the image into an array,that array consists of pixels a=imread("give your imagepath"); now convert the array of pixels into binary by using the inbuilt function dec2bin, binaryvalues=dec2bin(a); now you get the binary values in single column

[Walter Roberson]

hemalatha, that is not quite correct. You need

binaryvalues = reshape( (dec2bin(a, 8)-'0').', [], 1);

to get the binary values in a single column (presuming that the image was uint8 data type.)
