Terrain map summary elements
First Claim
1. A method for analysis of image data for subject content comprising:
- (a) performing at least one pass through a frame of said image data;
(b) generating a base terrain map from said pass through said frame of said image data, said base terrain map comprising a plurality of base data members that indicate the content of said image data, the plurality of base data members being selected from the group consisting of an average altitude parameter, a degree of slope parameter, a direction of slope parameter, a horizontal smoothness parameter, a vertical smoothness parameter and a jaggyness parameter; and
(c) generating at least one terrain map summary hierarchically removed from said terrain map, said at least one terrain map summary including a plurality of data members that summarize the content of said plurality of base data members.

Abstract
Method and system for image data analysis, by making use of a Terrain Map Summary Element (TMSE) data structure, in which a Terrain Map data structure provides processed primitive data about each 2×2 kernel of pixels from an original image. The new TMSE is a hierarchical multiple-level or tiered structure of such Terrain Map elements, in which each successive Terrain Map level summarizes, for example, 16 lower level elements or member. By providing such a hierarchical nature of the map elements, richness is enhanced by each higher element because every element of each successively higher level map summarizes the data from elements of the lower level map. For example, in a five-level Terrain Map Summary Element structure according to the disclosure, each element or member of the fifth level contains information summarizing data about 256K pixels.

11. A data analysis terrain map summary elements structure comprising:
-
a base terrain map data structure generated from at least one pass through a frame of original image data, said base terrain map including a plurality of base data members that indicate the content of said image data, the plurality of base data members being selected from the group consisting of an average altitude parameter, a degree of slope parameter, a direction of slope parameter, a horizontal smoothness parameter, a vertical smoothness parameter and a jaggyness parameter; and a set of tiered terrain map summaries hierarchically successively removed from the base terrain map, each terrain map summary from the set of tiered terrain map summaries having a plurality of members that summarize content of members of the terrain map summary immediately below it or content of the plurality of base data members of the base terrain map.

12. A non-transitory processor-readable medium storing code representing instructions configured to cause a processor to:
-
define a plurality of portions of a frame of a video image, the frame of the video image including a plurality of pixels, each portion from the plurality of portions including pixels from the plurality of pixels of the frame; receive a plurality of pixel values, each pixel value being associated with a pixel from the plurality of pixels; calculate values for a plurality of base data members using pixel values associated with the pixels of each portion from the plurality of portions, the plurality of base data members summarizing the pixel values associated with the pixels of each portion from the plurality of portions of the frame; define a plurality of groups, each group from the plurality of groups including at least two portions from the plurality of portions; and calculate values for a plurality of summary data members that summarize the base data members of the at least two portions within each group from the plurality of groups. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
