Enhance Filter                                  Description

                     Antialiasing                  It eliminates distortions from a picture while downscaling it to a relatively
                                                   lower resolution to smooth out the edges.
                     Deinterlacing                 This process removes extraneous and undesirable picture information from
                                                   interlaced image frames. The choice to maintain the interlacing of odd and
                                                   even image fields is present.
                     Despeckle                     It cleans up minor flaws from the present image area, like noise particles. The
                                                   median setting has two options: adaptive, which analyses the histogram of
                                                   the chosen image’s surrounding area, or recursive, which performs repeated
                                                   actions to improve the image. The radius measurement could be adjusted to
                                                   eliminate flaws. For the image’s lighter and darker cells, Black level and White
                                                   level options are also available.

                     Destripe                      This technique eliminates the vertical stripes in a picture that are the result of
                                                   mediocre scanners. The strips are removed by adding a pattern that obstructs
                                                   the picture. The “Width” choice that is offered with this filter is used to adjust
                                                   the filter’s strength.
                     NL (Non-Linear)               This  filter  combines  the  Despeckle,  Sharpen,  and  Smooth  enhancement
                                                   functions to enhance the overall look of focus, rather than just on a specific
                                                   area of the picture. It removes swollen eyes and makes adjustments. It may
                                                   establish a threshold value to reduce the intensity of red eye.
                     Sharpen (UnSharp Mask)        It is helpful for enhancing edges and any kind of noise in digitised images to
                                                   compensate for lack of sharpness. The user can preview the image and adjust
                                                   the sharpness. Without adding more noise, it sharpens the picture. With the
                                                   help of the Radius, Amount, and Threshold parameters, the user can choose
                                                   where sharpening is necessary and with what level of power.

              Distorts Filter

                     ApplyLens                     It overlays the picture with an elliptical lens.
                     Emboss                        It  makes  the  picture  appear  to  be  embossed.  Option  settings  include  an
                                                   image’s azimuth (a component of lighting), elevation, and depth.
                     Engrave                       It creates an engraving appearance similar to that of coins. Based on the
                                                   value of the underlying pixels, black and white horizontal lines with various
                                                   heights are used to simulate the image.
                     Lens Distortion               It enables the correction of distortion brought on by the camera lens.

                     Kaleidoscope                  Gives the appearance of a kaleidoscope in the picture.

                     Mosaic                        It divides the picture into numerous square or polygonal tiles that are slightly
                                                   raised and attached to one another to resemble a mosaic. It offers options
                                                   for selecting Tile size, Height, Direction, and Color Variation, among others.
                     Polar Coordinates             With all potential polar coordinates and intermediates, it provides a circular
                                                   or rectangular representation of the image.
                     Ripples                       Pixels are moved around in a wave pattern. It has several choices, including
                                                   Wrap Type, Orientation, and Edges.
