System for automated screening of security cameras

A method for real-time analysis of video image data for subject content, said method comprising the steps of:

• (a) performing at least one pass through a frame of said video image data;
• and
• (b) generating a terrain map from said pass through said frame of said video image data, said terrain map comprising a plurality of parameters wherein said parameters indicate the content of said video image data, wherein said parameters comprise:
• an average altitude parameter which measures an average value of four pixels in the center of a 2×2 kernel in said frame of said video image data;
• a degree of slope parameter which measures an absolute difference between a highest average value and a lowest average value calculated by said average altitude;
• direction of slope parameter which measures a direction of slope based on said highest average value and said lowest average value calculated by said average altitude;
• a horizontal smoothness parameter which measures a consistency of change in horizontal direction from a lowest pixel to a highest pixel in said frame of said video image data;
• a vertical smoothness parameter which measures a consistency of change in vertical direction from a lowest pixel to a highest pixel in said frame of said video image data;
• and
• a jaggyness parameter which measures an offset in pixels between odd and even fields for a target segmented from said frame of said video image data.

A method for real-time analysis of video image data, said method comprising the steps of:

• (a) performing a single pass through a frame of said video image data;
• and
• (b) generating a terrain map from said pass through said frame of said video image data, said terrain map comprising a color space calculation wherein said color space calculation comprises:
• a color degree parameter which measures how far a color is from gray scale;
• and
• a color direction parameter which measures color based on a two-dimensional color analysis.
