proper-closing A finite combination of successive closing and opening operations that you
can use to fill small holes and smooth the boundaries of objects.
proper-opening A finite combination of successive opening and closing operations that you
can use to remove small particles and smooth the boundaries of objects.
Q
quantitative analysis Obtaining various measurements of objects in an image.
R
real time A property of an event or system in which data is processed as it is acquired
instead of being accumulated and processed at a later time.
resolution The number of rows and columns of pixels. An image composed of m rows
and n columns has a resolution of
reverse function Inverts the pixel values in an image, producing a photometric negative of
the image.
RGB A color encoding scheme using red, green, and blue (RGB) color
information where each pixel in the color image is encoded using 32 bits:
8 bits for red, 8 bits for green, 8 bits for blue, and 8 bits for the alpha value
(unused).
RGB U64 A color encoding scheme using red, green, and blue (RGB) color
information where each pixel in the color image is encoded using 64 bits:
16 bits for red, 16 bits for green, 16 bits for blue, and 16 bits for the alpha
value (unused).
Roberts filter An edge detection algorithm that extracts the contours in gray level,
favoring diagonal edges.
