In-flight Measurements

I2R offers an image quality assessment service using our Image Quality Estimation tool - IQETM Spatial. In-flight imagery over urban features is used to quantify image quality. The technique does not require special imagery acquired over predetermined targets, and can accept all standard image file formats. IQETM Spatial has been extensively validated against industry standard methods and targets funded by NASA and DHS.

Potential users of IQETM Spatial services are sensor and image providers who want to monitor or validate in-flight performance, organizations that purchase high to moderate resolution remotely sensed imagery, software developers interested in optimizing image restoration algorithms, and intelligence agencies interested in automated NIIRS estimation.

By statistically examining imagery acquired over urban environments that contain roads, buildings and other edge features, I2R Provides customers with:

• Quantified spatial resolution measures including: Modulation Transfer Function (MTF) curves, MTF at the Nyquist frequency, MTF at half the Nyquist frequency and Relative Edge Response (RER) in the in-track and cross track direction.
