| | Date : 2016/12/07 |
| | Version : 0.26 |
|
| |
|
| Date Format: year/month/day
| | * Fixed a long standing unit test issue where convolve unit test would some times on some systems erratically fail |
| | | ** Appears that sometimes the random numbers caused a buffer overflow for U8 images |
| ---------------------------------------------
| | ** Now why it didn't have the exact same numbers every time when it has a fixed seed is disturbing... |
| Date : 2012/05/13
| | * Renamed EquirectangularTo* to *ToEquirectangular |
| Version : Alpha 0.8
| | ** Those classes convert pixels in * coordinates into their location in the equirectangular image |
| | | ** They are used to generate a * image from equirectangular |
| '''IMPORTANT''' Discard old calibration files and calibrate again with latest code!
| | * Float 32bit auto coding switched over to using auto64fto32f library |
| | | * TypeInterpolate is now InterpolationType for consistency |
| * Added processing monitor to CalibrateStereoPlanarGuiApp
| | * Examples |
| * Fixed bug in Zhang99 calibration where Rodrigues coordinates were being parameterized incorrectly | | ** InterpolatePixel added |
| ** Calibration results would be less accurate, but have a lower residual due to the increased degree of freedom
| | ** Image blur added |
| * Added analytic Jacobian to Zhang99
| | ** Non-Maximum Suppression added |
| ** Decided not to use it since it produces same estimation parameters as numerical.
| | * Demonstrations |
| * Added functions for creating detectors in FactoryPlanarCalibrationTarget
| | ** Improved DemonstrationInterpolateScaleApp (renamed also) |
| ** changed code to reference those functions

| *** Five region adaptive: Hirschmuller, et. al. "Real-Time Correlation-Based Stereo Vision with Reduced Border Errors," 2002 | | * Visualization |
| * IntrinsicParameters
| | ** Removed a bad +PI/2 from ellipse rendering. |

| | * SnapToEllipseEdge * Fixed bug where it was only performing one iteration no matter what |
| * RectifyImageOps
| | * Circle Asymmetric Grid Target |
| ** Fixed bug in functions that adjusted the rectification for viewing. If left handed the coordinate systems got messed up
| | ** Fixed issue which was causing clusters not to form by not limiting number of neighbors within X distance |
| * Changed allInside() so that the annoying single pixel black region is gone
| | ** When clustering ellipses orientation and major/minor axis size is now taken in account. |
| ** RectifyImageOps and LensDistortOps
| | ** Significant net improvement in regression tests, only drop in performance in blurred images |
| * FactoryCornerDetector
| |
| ** Added flag for weighted KLT and Harris
