2020-08-04 | Update testdata to reflect updated integral package | Nick White | |
2020-08-04 | Improve sauvola window code slightly | Nick White | |
The sauvola and integral image version are still slightly different, irritatingly. | |||

2020-07-26 | Switch to integralimg 0.3.0 and use the new functions for integral sauvola | Nick White | |
2020-07-24 | Update commands to use the updated interfacesv0.2.0 | Nick White | |
2020-07-24 | Make sideways() work on any image.Image | Nick White | |
2020-07-24 | Fix failing tests; happily the test was just not correctly written | Nick White | |
2020-07-23 | Update to v0.2.1 of integralimg, and improve various things | Nick White | |
- Improve integral sauvola by rounding threshold correctly - The Sauvola functions can now process any image.Image, not just an image.Gray - Add ImageWindower interface and use it to generalise wipesides.go - Rely on Bounds() for image bounds rather than implementation- specific stuff in integralimg Note that a couple of the wipesides tests are now failing. It's possible that this is due to fixed or introduced bugs (let's hope the former) changing sensible thresholds. Will need to look into this and sort it. | |||
2020-07-23 | Improve sauvola by ensuring threshold is rounded correctly before comparison | Nick White | |
2020-07-20 | [pggraph] gofmt | Nick White | |
2020-07-20 | [pggraph] Simplify and correct x ticks | Nick White | |
2020-07-20 | Add pggraph tool | Nick White | |
2020-07-14 | Do vertical wiping before horizontalv0.1.4 | Nick White | |
This should help the horizontal wiping, hopefully, as there will be less inconsistent noise inside of the text area it processes. | |||
2020-07-13 | Improve wiper algorithm | Nick White | |
Several changes made to wiper to improve things: - If findbestedge finds more than one 'best' line, choose the middle one, rather than the first. - findbestedge selects the line with the lowest number of black pixels, rather than (erroneously) the highest. - Added a findedgesOutin() function, which finds edges like findedges() but looking from the outside edges of the image inwards, rather than from the inside out. More testing is needed to decide whether this is useful; initial testing showed very little difference, but that was limited to lightly binarised images. This is in use by VWipe() at present, where worries about several gutters thanks to the edges of other pages aren't present. - Added separate vwsize, vthresh and vmin arguments to WipeFile so that vertical wiping can have different parameters (which is very important for good quality vertical wiping). - Updated wiping tests. - Rewrote the wipe cmd to use WipeFile() directly. | |||

2020-03-03 | Add experimental vertical wiping feature to wiper | Nick White | |
2020-03-03 | Add edge detection tests for wipesides | Nick White | |
These should be nice and robust to small changes that are still valid, as they don't depend on the output not changing, only on the detected sides being within appropriate limits. | |||
