| Issue: #718 | |||
| 2018-01-11 | tracker/pt: allow for reuse | Stanislaw Halik | |
| Issue: #718 This allows for replacing the camera and point extractor code. See `module.cpp' and `pt-api.hpp`. | |||
| 2018-01-10 | tracker/pt: add comment | Stanislaw Halik | |
| 2018-01-03 | tracker/pt: more accurate dynamic threshold | Stanislaw Halik | |
| 2017-12-21 | tracker/pt: default to natural grayscaling | Stanislaw Halik | |
| It's the most optimized opencv version. | |||
| 2017-12-02 | tracker/pt: use cv::Mat::reshape() to avoid memcpy | Stanislaw Halik | |

| 2017-10-27 | tracker/pt: fine-tune point brightness score | Stanislaw Halik | |
| 2017-10-27 | tracker/pt: simplify point extractor | Stanislaw Halik | |
| - no need to zero out floodfill areas, by its logic - let meanshift work with rect center as initial point - show extra points in gray | |||
| 2017-10-22 | tracker/pt: return focal length directly | Stanislaw Halik | |
| 2017-10-20 | tracker/pt: grayscaling modes work | Stanislaw Halik | |
| 2017-10-13 | tracker/pt, options: fix threshold slider | Stanislaw Halik | |
| It's only the tie_setting(slider_value, QSlider) that has race-free slider updates. Needed to update the threshold slider representation. Remove the tie_setting(int, QSlider) overload since it doesn't have the logic. Add a migration. Add base_value::notify() for use-cases like the checkbox updating the label. | |||
| 2017-10-13 | tracker/pt: add threshold slider state description | Stanislaw Halik | |
| Isolate point radius code and reuse it. | |||
| 2017-10-13 | compat/macros: fix "restrict" name clash | Stanislaw Halik | |
| 2017-10-10 | tracker/pt: comment typo | Stanislaw Halik | |
| 2017-10-08 | tracker/pt: grayscale methods work | Stanislaw Halik | |
| - fix a braino (don't divide by two) - default to exact averaging, not perceptual weighted - use more specific cv::addWeighted | |||
| 2017-09-23 | tracker/pt: fix braino | Stanislaw Halik | |
| Don't multiply red channel by 3 in 0->1 range. | |||
| 2017-09-22 | tracker/pt: add color extraction modes | Stanislaw Halik | |
| 2017-07-29 | tracker/pt: revert most 2.3.8 changes | Stanislaw Halik | |
| Remove contour usage. They're less precise than flood fill. Keep sensible changes. | |||
| 2017-07-26 | tracker/pt: scale min/max radius with resolution | Stanislaw Halik | |
| For 320x240 frames auto threshold min value of 2.5 was too big. Scale it linearly with frame size. | |||
| 2017-07-25 | tracker/pt: fix overlay | Stanislaw Halik | |
| The "fract_bits" constant wasn't used consistently in the 2nd cv::circle invocation. Drop the invocation. | |||
| 2017-07-25 | tracker/pt: fix weight formula | Stanislaw Halik | |
| 2017-07-25 | tracker/pt: compute blob weight | Stanislaw Halik | |
| The formula is total brightness over sqrt(radius). | |||
| 2017-07-20 | tracker/pt: fix build on Linux | Stanislaw Halik | |
| GNU expects ODR for `int' constexpr members. | |||
| 2017-07-16 | compat/math-imports: use it | Stanislaw Halik | |
| 2017-07-07 | Unsigned cast reformat | attila-csipa | |
| 2017-06-30 | tracker/pt: reformat lightly | Stanislaw Halik | |
| 2017-06-22 | tracker/pt: replace point extraction algorithm | Stanislaw Halik | |
| Profiling over a longer time period showed a bottleneck while iterating pixels with `cv::floodFill()'. Contours are actually faster, and we have MeanShift to establish the proper center basing on pixel intensities. | |||
| 2017-06-19 | tracker/{aruco,pt}: convert camera image with BGR weights | Stanislaw Halik | |
| We were using the wrong weights for all the years. Fuck me. | |||
| 2017-06-18 | tracker/pt: tweak meanshift cpu usage | Stanislaw Halik | |
| 2017-06-12 | tracker/pt: cleanup | Stanislaw Halik | |
| Also, changing "f" typedef to "float" won't break the build anymore. | |||
| 2017-06-12 | tracker/pt: fix LED radius offset | Stanislaw Halik | |
| 2017-06-11 | tracker/pt: show detected blobs as circles | Stanislaw Halik | |
| 2017-04-18 | many: use std::f{max,min} for floating-point values | Stanislaw Halik | |
| 2017-04-18 | tracker/pt: revert extractor change | Stanislaw Halik | |
| 2017-04-18 | tracker/pt: replace original blob center search with meanshift | Stanislaw Halik | |
| The functions are almost identical so why not. I removed several bits: - weighting by squared pixel value is bad. weight by pixel value instead. - making the ROI twice as big doesn't make sense and makes for misdetected blobs. remove it. - switch radius coefficient to something doing less iterations. - sprinkle some __restrict pointer qualifier. - cv::floodfill invocation had some hardcoded flag value. - point radius circle and the bullseye line length weren't adjusted by scaling ratio. while the circle fitted the radius tightly, it was now clutter, so I removed it, leaving only the properly-scaled bullseye. - brightness had to go sadly since it's not accumulated anymore. | |||
| 2017-03-03 | tracker/pt: show average point radius on the displayopentrack-2.3.1_fix3 | Stanislaw Halik | |
| Helps with choosing automatic threshold slider position. | |||
| 2017-02-21 | tracker/pt: change meanshift kernel size coefficient | Stanislaw Halik | |
| From my usage the value of 1.5 is excessively conservative. | |||
| 2017-02-21 | tracker/pt: resize the camera feed, not the preview | Stanislaw Halik | |
| This makes the point size text and point crosses not alias due to the resize. Due to nice pixel coordinate system, the cross-drawing lambda only needs minimal changes. | |||
| 2016-12-16 | tracker/pt: refactor camera info handling | Stanislaw Halik | |
| - Pass `struct CamInfo' rather than several elements separately - Reformat - Return `struct CamInfo' together with the frame since then it's always valid - Move the focal length formula into `struct CamInfo' - Remove incorrect focal length formula rather than #if 0 - Pass some stuff by reference and not by pointer | |||
| 2016-12-10 | tracker/pt: make overlay look more of the same on 320x240 as 640x480 | Stanislaw Halik | |
| 2016-12-09 | tracker/pt: show right overlay wrt frame size | Stanislaw Halik | |
| 2016-12-09 | tracker/pt: use the right delta for iteration stop | Stanislaw Halik | |
| 2016-12-09 | tracker/pt: inline meanshift eval fun | Stanislaw Halik | |
| 2016-12-09 | tracker/pt: improved precision and noise rejection by mean shift filtering | DaMichel | |
| 2016-11-12 | tracker/pt: refactor | Stanislaw Halik | |
| - separate .{cpp,hpp} for few classes - don't include namespaces globally; harmless but looks bad anyway - class with all public members to struct | |||
