  1. Version 1.6.7489.24864 Minor improvements (kernel matrix accuracy and to8bit clamp function a bit more efficient).
  2. @Foxxey Danke @Seerose It's my pleasure to contribute here !
  3. Version 1.5.7467.22643 Source
  4. Slight edge boost Last version 1.6.7489.24864 [ 06 July 2020 ] Download link > > > Download Location: Effects -> Photo Corresponding source is available in the last post. Plugin description This plugin enhances image edges using unsharp mask method. It provides the possibility to apply sharpen only to the image luminosity in order to avoid chromatic noise amplification. Illustration on a stenope (blurry) photography
  5. Version 1.5.7466.17310 Fix crash with small image using mirror border handling. Improve accuracy of the matrix coefficients ( Math.Sin( k * Pi ) = 0). Source
  6. Version 1.4.7461.19568 Optimization in the rendering method. Test if the rectangle boundary is far enough from the border allowing useless limit tests when getting surface color pixels.
  7. Version 1.3.7456.16099 Computation have been optimized. The kernel matrix has symmetries allowing to divide its storage by 4. Convolution has been optimized too the symmetry allows to factorize multiplications which divide the number of multiplication by four.
  8. After checking FFT results I noticed diamond shaped filter was leaking. There were a bug in the coefficient creation. Here the fixed version v1.2. The results show a better retention of unwanted frequencies. Minor upgrade : The filter cutoff parameter has four states corresponding to the number of lobes of the Sinc functions (4-8-12-16).

  9. Hi Reptillian, I used ImageMagick to make the spectrum images which are created using FFT. My plugin uses convolution method (Sinc filters). FFT with spectrum mask is a powerful tool and versatile but I think it's hard to get into that. My goal is make a toolkit allowing image processing like FFT but lighter in term of computation resources and easier to use. (Goal is today far from filled )

  11. WaveToolBox Last version 1.5.7466.17310 [ 10 June 2020 ] Download link > > > Download Change log summary: Fix crash with small image using mirror border handling Improve matrix coefficient accuracy Location: Effects -> Advanced.

  12. Hello Djisves, Thanks for the feedback ! I called this plugin tool box because it can be used for many things and I think you're right render may not be a good place (I hesitated a lot in fact). I may change the location to advanced it would be more suitable. I test what I deliver so I can say it's ok to be run. I will fix the menu issue and add a parameter to tune the Sinc filter before delivering in Plugins - Publishing ONLY!. Have a nice day,
  13. Hi, I deliver the first version of the WaveToolBox plugin. The goal is to provide advanced settings for processing image using Sinc filters. This is work in progress but this first version already offers the following settings: - Kernel shape (square, disc and diamond) (diamond is not a shape really common) - Kernel radius, literally the size of the box filter in pixels - Border handling (uniform color, extend, mirror) - Global contrast The processing may be heavy in case of large radius; the plugin is practical but lack of optimization.
  14. Hi ! I modified the engine of my sharpening plugin, the sharpen amount is now following the standard. I changed how the sharpen is applied. The slider has a nonlinear effect on result allowing to have more range. (Math enthusiast will spot easily the sequence of values used). And the source code. // Name: Slight edge boost // Submenu: Photo // Author: Pascal Ollive // Title: Slight edge boost // Version: 1.4 // Desc: Gaussian unsharp mask // Keywords: Sharpening|Gaussian|filter // URL: // Help: #region UICode IntSliderControl sliderValue = 5; // [0,
