IMAGINE Subpixel Classifier™ is a leading image classification tool for advanced spectral analysis and interpretation. Subpixel Classifier provides dynamic searching and quantifying tools, enabling users to quickly extract the most comprehensive information from spectral imagery.

IMAGINE Subpixel Classifier is a state-of-the-art, supervised classifier that detects and reports whole and subpixel occurrences of a specific Material of Interest in multispectral imagery. IMAGINE Subpixel Classifier derives a signature for a specific material, groups all pixels in an image as either containing the material or not, and classifies all pixels that do contain the material into classes based on how much of the material they contain. It is a fully integrated, add-on application module to ERDAS IMAGINE.

IMAGINE Subpixel Classifier allows you to:

• Detect a specific Material of Interest
• Automatically search for a specific Material of Interest in multiple scenes
• Generate purer spectral signatures and residuals
• Create more complete classifications
• Inventory the specific Material of Interest in an image
  
  
  Benefits
• Classify objects smaller than the spatial resolution of the sensor
• Discriminate specific materials in mixed pixels
• Detect materials that occupy from 100% to as little as 20% of a pixel
• Report the fraction of material present in each pixel classified
• Develop signatures portable from one scene to another
• Correct imagery for atmospheric effects
• Search broad-area images quickly to detect small or large features mixed with other materials
  
  
  Features:
• Powerful, low cost alternative to ground survey, field sampling, or high resolution imagery over wide areas or in remote locations 
• Fully integrated with ERDAS IMAGINE
• Accepts airborne and satellite multispectral imagery such as Landsat Thematic Mapper, SPOT, IKONOS, and QuickBird multispectral imagery
