How do you get pixel coordinates in Matlab?

You can also obtain pixel value information from a figure with imshow by using the impixelinfo function. To save the pixel location and value information displayed, right-click a pixel in the image and choose the Copy pixel info option. Image Viewer copies the x- and y-coordinates and the pixel value to the clipboard.

How do I check pixel value in Matlab?

To determine the values of one or more pixels in an image and return the values in a variable, use the impixel function. You can specify the pixels by passing their coordinates as input arguments or you can select the pixels interactively using a mouse.

What is spatial coordinates in image processing?

Spatial coordinates enable you to specify a location in an image with greater granularity than pixel coordinates. Such as, in the pixel coordinate system, a pixel is treated as a discrete unit, uniquely identified by an integer row and column pair, such as (3,4).

What is used to specify co ordinates of the image?

Intrinsic Coordinates

By default, the toolbox defines spatial image coordinates using the intrinsic coordinate system. This spatial coordinate system corresponds to the image's pixel indices. The intrinsic coordinates (x,y) of the center point of any pixel are identical to the column and row indices for that pixel.
