    摘要： The invention relates to a method (400) for classifying a terrain type in an area. The method comprises the step of obtaining (410) a plurality of overlapping aerial images of the area. The method also comprises calculating (430) at least one terrain type index for each part of each of the aerial images which lies in the area, where the at least one terrain type index represents the terrain type. The method also comprises the step of determining (440) at least one terrain type index for each part of the area based on the calculated at least one terrain type index for each part of each of the aerial images; and the step of classifying (450) the parts of the area for which at least one pre-determined conditions is met as containing the terrain type, wherein at least one of the at least one predetermined condition relates to a value of the determined at least one terrain type index. The invention also relates to a system (600), a computer program and a computer program product

    摘要： Automatic characterization or categorization of portions of an input multispectral image based on a selected reference multispectral image. Sets (e.g., vectors) of radiometric descriptors of pixels of each component of a hierarchical representation of the input multispectral image can be collectively manipulated to obtain a set of radiometric descriptors for the component. Each component can be labeled as a (e.g., relatively) positive or negative instance of at least one reference multispectral image (e.g., mining materials, crops, etc.) through a comparison of the set of radiometric descriptors of the component and a set of radiometric descriptors for the reference multispectral image. Pixels may be labeled (e.g., via color, pattern, etc.) as positive or negative instances of the land use or type of the reference multispectral image in a resultant image based on components within which the pixels are found.

    摘要： A method (100) of enhancing an image includes increasing sampling rate of a first image (102) to a target sampling rate to form an interpolated image (146). The method also includes processing a second image (104) through a high pass filter (114) to form a high pass features image (116), wherein the second image (104) is at the target sampling rate. The method also includes extracting detail (118) from the high pass features image (116) relevant to the first image (102), merging (120) the detail from the high pass features image (116) with the interpolated image (146) to form a prediction image (106) at the target sampling rate, and outputting the prediction image (106).
