Uses a Sobel edge detector to highlight sharp changes in intensity in the active image or selection. This filter uses the following weighting factors to replace each pixel with a weighted average of the 3x3 neighborhood. Increases contrast and accentuates detail in the image or selection, but may also accentuate noise. This filter replaces each pixel with the average of its 3x3 neighborhood. Click on the image to see an example of an analysis based on the data from the Digitization plug-in, and obtain the plug-in for free.Home | contents | previous | next Process Menuīlurs the active image or selection. The coordinates can then be used for further analysis. By clicking on these features their coordinates are saved to a textfile (CSV). The Digitization plug-in has been designed to digitize positions of features in large image files. Includes the forward and inverse Fourier transform.Ĭlick on the image to see how effectively frequency components (raster pattern as well as diagonal features) have been removed, and obtain the plug-in. in removing printing screens / rasters to avoid Moiré-patterns, while retaining as much detail as possible. It uses one of the fastest implementations of the Discrete Fourier Transform and has many applications, such as separating or removing periodical patterns, and analyzing and enhancing certain periodical patterns. Chirokov to make filtering in the frequency domain available for free. The Fourier transform plug-in has been designed by A.V. You can take a picture of a document or painting under an angle to avoid unwanted reflections and resulting loss of detail and color quality, and then turn it into a perpendicular view with this plug-in.Ĭlick on the image to see how a normal picture can be transformed into a virtual helicopter view, and obtain the plug-in. It takes the guesswork out of making square things square! It uses 4 source and destination controlpoints that are mapped onto eachother, and the whole image is transformed accordingly. The Warping plug-in performs precise geometrical transformations also known as projective mapping or image warping. In forensic science it is used in the examination of documents, fingerprints, and shoe marks, to dramatically enhance the visibility of traces and remove obscuring features.Ĭheck out the image processing examples and obtain the plug-in.Ĭlick on the example to see the result. It has been used successfully for varied tasks such as: recovering erased or crossed-out text, removing stains and silvering in restoring photographs, and even digital simulation of Infrared photography through color replacement. The popular Color Deconvolution plug-in was originally developed for forensic science, to make the invisible visible by an advanced algorithm for color separation. The color deconvolution plug-in, warping plug-in, and their try-out versions are available in 32bit and 64bit version.

You do not need to have Photoshop™ to be able to use the plug-ins, you can also use them with free programs like XnView. Although the plug-ins on this site have been designed for forensic use they have plenty of applications for image processing enthusiasts in general.
