Added primitives to compute the basic statistics for the
single-channel types going beyond a single byte of data for their
channel, and integrated them into 'crimp statistics basic'. No
histogram for these, nor median (which is computed from the
histogram). Plus demo.
Added the extended statistics to the hough demo. check-in: fc24897d1e user: andreask tags: ak-experimental | |

| 18:25 | Back to the hough transform, this implementation needs the background (non-line) color, to represent empty buckets. check-in: 5f08ca4dd3 user: andreask tags: ak-experimental | |
| 07:42 | Fixed a number of older C primitives to use the proper macro for image argument processing check-in: e24f31bc75 user: andreask tags: ak-experimental | |
| 07:41 | Fix the overzealous changes from [007a79aa59] check-in: 9165920582 user: andreask tags: ak-experimental | |
| 06:34 | Reworked internals to avoid ensemble overhead, calling on the commands directly check-in: 007a79aa59 user: andreask tags: ak-experimental | |
| 06:32 | Fixed typo check-in: f1177dd0eb user: andreask tags: ak-experimental | |
| 00:25 | First work on the hough transform. check-in: e544dbf0ae user: andreask tags: ak-experimental | |

Bringing the warp branch back into the main development line.
With this the following tickets are fixed/implemented:
| |
| 06:53 | Merged from [3440950d67] Closed-Leaf check-in: 88563a96b1 user: andreask tags: warp-experiment | |
| 06:42 |
Default interpolation switched from nearest neighbour to bilinear.
Re-added a resize method, now based on projective warp. Renamed the 'crimp warp warp' to 'crimp warp field', in deference to the vector fields providing the sampling coordinates. And yes, it is a bit tongue-in-cheek re StarTrek. Implemented the primitives for 'warp field'. Demo for 'warp field', a blur mode like light scattering through milky acryl. Documented 'resize, 'warp field' and the 'transform' methods. New demos for quadrilateral mapping. check-in: 5a58eae505 user: andreask tags: warp-experiment | |
| 04:58 | Fixed missing undef of SAMPLE macros check-in: b82e53528b user: andreask tags: warp-experiment | |
| 03:20 | Use explicit choice of interpolation method in all warp demos check-in: ffc482dad3 user: andreask tags: warp-experiment | |
| 03:19 | Fixed problems with transform setup, boundary calculations were off check-in: 0bd668ba6e user: andreask tags: warp-experiment | |

| 07:48 | Tweaked the names for transform inversion and chaining, and extended the latter to take an arbitrary number of transform instead of just two. check-in: 80a80a9a34 user: andreask tags: warp-experiment | |
| 04:18 | Actually implemented the bicubic interpolation now. The edge cases, i.e. border pixels however do not look very nice yet, but fuzzy. This requires a bit more research. check-in: 795404435b user: andreask tags: warp-experiment | |
| 03:18 | Staring at the code and then instrumenting it and looking at the generated log I came to the conclusion that the code for the 'bicubic' interpolation is actually the 'bilinear' one. Oops. Renamed and updated all comments. Added wikipedia reference link. check-in: 822cab159f user: andreask tags: warp-experiment | |
| 00:26 | Extended the projective warp primitives with bicubic interpolation, snarfed from the matrix method. check-in: c888db113c user: andreask tags: warp-experiment | |

| 23:58 | Completed the nearest neighbour primitives (projective warp) with all image types using single bytes in their channel handled by a single primitive. Additional demos, for color, and scaling. Fixed bug in handling of -interpolate option, was a no-op. check-in: f4c266208f user: andreask tags: warp-experiment | |
