Wavelet Sharpen Ver.0.1.2 Win_64bit

 (wavelet-sharpen.exe)

In menu: Filters ➤ Enhance ➤ Wavelet sharpen ...

The wavelet sharpen plugin increases apparent sharpness of an image. The amount of unsharpness in the original image can be taken into account.

From the plugin author's information:

There are two circumstances that makes it necessary to use the sharpen filter:

1. To reduce the effects due to aliasing of an picture which is in focus.
   a) Set the amount of sharpening using the slider.
   b) You may want to have the checkbox 'Sharpen luminance only' activated in order to avoid having colour artifacts (especially in noisy images).
   c) The sharpening radius can be left at 0.5.

2. To sharpen a picture which is out of focus.
   a) Set the amount of sharpening rather high (at first).
   b) Adjust the sharpening radius using the slider to choose the frequency  part in the image which is to be increased in contrast. This means for  blurred pictures you may want to set the value high (which sharpens slow-ly varying image features, leaving high frequency noise alone). Use low values if the image has many details.
   c) Set the sharpening amount back to a value that pleases your eye.
   d) You may want to have the checkbox 'Sharpen luminance only' activated in order to avoid having colour artifacts (especially in noisy images).
