	PRICE can work with filters based on convolutions, either entered custom, or by applying a frequency low-pass or frequency high-pass filter. These frequency filters are applied in the frequency domain using a 2D discrete Fourier transform and thus they are of very high quality but expensive in terms of computation and memory. A low pass filter is roughly a "blur" while a high-pass filter shows the edges of an image and can be used for edge enhancement. The custom convolution kernel of 5x5 may also be used for thus effects and the documentation on the website offers both numeric as visual examples.

	PRICE also offers a series of manipulations in the "enhancement" category. Basic controls like brightness and contrast controls are present. A Median filter is offered for noise reduction and different options about its application are offered, which allow to customize the effect regarding both strength as its impact on the edges and corners.

 features =
 PRICE can be used as a simple image viewer, it treats images as documents and thus multiple images can be opened and viewed at different zoom levels.
-PRICE is able to perform basic image opertions like rotation, mirroring, cropping and scaling. PRICE also shows information about the image that can be useful for image analysis, like histograms (in case of an RGB image the colors are stacked so to give also a clue about the brightness) as well as the modulus of the FFT and thus show the image in its frequency domain.
