MTF Compensation
MTF Compensation reduces the impact of the chart material on measured imaging system MTF. This compensation greatly increases the resolution suitability of test charts, enabling one to test with a lower precision chart or to accurately test at a closer distance where uncorrected MTF results would be degraded.
Geometric Calibration
Imatest produces a geometric calibration from a projective camera model and images of checkerboard patterns. A geometrically calibrated device provides a mapping between pixel coordinates and real-world position, e.g., for stereo imaging depth perception.
Improved distortion calculation
Imatest Checkerboard and SFRplus modules now support an enhanced set of distortion models and provide faster and more accurate distortion coefficient and center of distortion estimations.
Temporal noise from multiple files
ISO 15739 compliant temporal noise measurements are now available in Multicharts & Multitest.
Sony AYA Image Acquisition
Imatest now supports direct image acquisition from Sony sensor development boards through the Sony AYA software tool.
Synthetic raw creation/Remosaic
Create pseudo-off-the-sensor data through image processing when the raw information is not available.
