grayscale image into matrix

hello sir,

am on a project, for which i need to convert a image into gray scale and access the matrix of each block , how will i get those matrix

[Rik]

Images in Matlab are already matrices. What do you mean with block? Does that definition match the one in the blockproc function?

Comment posted as answer by Swathi D:

not actually a blockproc, certain part of my image has blocks and i want to know the matrix of that block

[Rik]

It is not clear what you mean. Can you provide an example input and output?

[Swathi D]

consider this as my image can i get the matrix of the blocks within the image

[Rik]

Does the rectangle with rounded count as a block? Can you count on sharp corners? Does the outer rectangle count as a separate object?

You can probably use bwlabel and loop through the objects to determine if they fit your requirements.

[Swathi D]

yup those are counted as blocks

thank you

Can you share the real image, with mentioning the target regions?
