HSI) color space. The different colored objects in the image correspond to separate clusters of points in color space, although the clusters corresponding to different objects may well overlap. The hue and saturation of an object are normally dic- tated by the light-reactive properties of its dye or stain— how it absorbs, reflects, or emits light. The intensity, however, is seriously affected by illumination and view- ing angle. Uneven illumination, for example, normally has much more effect on intensity than on the two color parameters. Thus it may be productive to segment the image in the hue-saturation plane {, on the color circle) rather than in three-dimensional color space, thereby ig- noring intensity altogether. Object measurement and classification Once the objects in the image have been identified, they can usually be measured in one of the color-channel images. Sometimes two or more color-channel images can be combined to produce a monochrome image for analysis. Further, some objects may be present in different.
