Image Types
Images can be b inary, intensity (grayscale), or RGB.
Binary Images
Binary images are represented by a Boolean matrix of 0s and 1s, which
correspond to black and white pixels, respectively.
For more information , see “Binary Images” in the Im age Proces sing Toolbox
documentation.
Intensity Images
Intensity images are represented by a matrix of i ntensity values. W hile
intensity images are not stored with colormaps, you can use a gray colormap
to display them.
For more information, see “Grayscale Images” in the Image Processing
Toolbox documentation.
RGB Images
RGB image s are also known as a true-color images. With Video and
Image Processing Blockset, these images are represented by an array,
where the first plane represents the red pixel intensities, the se cond plane
represents the green pixel intensities, and the third plane represents the
blue pixel intensities. In Video and Image Processing Blockset, you can
pass RGB images betw een blocks as thre e separate color planes or as one
multid imensional array.
For more i nfo rmation, see “Trueco lor Images” in the Image Processing Toolbox
documentation.
Video in Video and Image Processing Blockset
Video data is a series of images over time. Video in binary or intensity format
is a series of single images. Video in RGB format is a series of matrices
grouped into se ts of three, where each matrix represents an R, G, or B plane.
