2020-08-17Fix some error printing in PreProcMulti()v0.4.0Nick White
2020-08-17Have preproc and preprocmulti commands do vertical wiping tooNick White
2020-08-17Add vertical wipe to PreProcMulti(), and improve error messagesNick White
2020-08-04Slightly simplify a couple of wipesides.go functionsNick White
2020-08-04Update testdata to reflect updated integral packageNick White
2020-08-04Improve sauvola window code slightlyNick White
The sauvola and integral image version are still slightly different, irritatingly.
2020-08-04Update to replace integralimg package with integral packageNick White

2020-07-26Switch to integralimg 0.3.0 and use the new functions for integral sauvolaNick White
2020-07-24Update commands to use the updated interfacesv0.2.0Nick White
2020-07-24Make sideways() work on any image.ImageNick White
2020-07-24Fix failing tests; happily the test was just not correctly writtenNick White
2020-07-23Update to v0.2.1 of integralimg, and improve various thingsNick 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.
2020-07-23Improve sauvola by ensuring threshold is rounded correctly before comparisonNick White
2020-07-20[pggraph] gofmtNick White
2020-07-20[pggraph] Simplify and correct x ticksNick White
2020-07-20Add pggraph toolNick White
2020-07-14Do vertical wiping before horizontalv0.1.4Nick White
This should help the horizontal wiping, hopefully, as there will be less inconsistent noise inside of the text area it processes.
2020-07-13Improve wiper algorithmNick 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.

2020-05-04Have wipefile do vertical as well as horizontal wipingv0.1.3Nick White
2020-04-14Update integralimg dependencyv0.1.2Nick White
2020-04-14Improve documentation throughoutNick White
2020-03-05Add another top/bottom wipe testv0.1.1Nick White
2020-03-04Add vertical test to wipesidesNick White
2020-03-03Add experimental vertical wiping feature to wiperNick White
2020-03-03Add edge detection tests for wipesidesNick 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.

2019-10-02Add wipeonly queue and functionalityNick White
This is useful for prebinarised images, which don't need full preprocessing, but do require wiping, albeit with a more conservative threshold.
