Image Segmentation Data Set The instances were drawn randomly from a database of 7 outdoor images. The images were hand-segmented to create a classification for every pixel. Each instance is a 3x3 region.
Attribute Information
- region-centroid-col: the column of the center pixel of the region.
- region-centroid-row: the row of the center pixel of the region.
- region-pixel-count: the number of pixels in a region = 9.
- short-line-density-5: the results of a line extractoin algorithm that counts how many lines of length 5 (any orientation) with low contrast, less than or equal to 5, go through the region.
- short-line-density-2: same as short-line-density-5 but counts lines of high contrast, greater than 5.
- vedge-mean: measure the contrast of horizontally adjacent pixels in the region. There are 6, the mean and standard deviation are given. This attribute is used as a vertical edge detector.
- vegde-sd: (see 6)
- hedge-mean: measures the contrast of vertically adjacent pixels. Used for horizontal line detection.
- hedge-sd: (see 8).
- intensity-mean: the average over the region of (R + G + B)/3
- rawred-mean: the average over the region of the R value.
- rawblue-mean: the average over the region of the B value.
- rawgreen-mean: the average over the region of the G value.
- exred-mean: measure the excess red: (2R - (G + B))
- exblue-mean: measure the excess blue: (2B - (G + R))
- exgreen-mean: measure the excess green: (2G - (R + B))
- value-mean: 3-d nonlinear transformation of RGB. (Algorithm can be found in Foley and VanDam, Fundamentals of Interactive Computer Graphics)
- saturatoin-mean: (see 17)
- hue-mean: (see 17)
