                    Notes          Blur Filters

                                   Low Pass: Its used to delete sharp edges and detail from an image allowing smooth gradients
                                   and low-frequency detail.

                                     Caution Users can control the percentage and radius of the effect using the sliders.
                                   Jaggy Despeckle: To minimize distortion of an image we use the Jaggy Despeckle filter. It creates
                                   a soft and blurred final image.
                                   Directional Smooth: It is used to find out the direction in which we need to apply the greatest
                                   amount of smoothing, subtly smoothing edges and surfaces.

                                   Zoom: The zoom filter lets users create an effect that blurs pixels outward from a center point on
                                   an image. The amount of zoom can be handled at the user’s end.
                                   Radial Blur: It gives an image a blurred effect that radiates from a central point. Users have the
                                   options of repositioning the centre point, setting the intensity of the effect, choosing a blur node,
                                   and setting the quality of the output.
                                   Soften: Used to blur an image a little thereby retaining a high level of detail. The filter can be
                                   applied to the entire image, or to part of it using a lens.

                                   Colour Transform Filters

                                   Bit Planes: To analyze gradients in images, we use the Bit Planes tool which reduces the image
                                   to basic Red Green Blue (RGB) components and emphasizes tonal changes.
                                   Halftone: It is an image that has been converted from a continuous tone image to a series of dots
                                   of various sizes to represent different tones. In order to produce a wider range of colours the
                                   screen angles can be adjusted.

                                   Contour Filters

                                   Find Edge: It locates and converts edges in an image to soft or solid fines. Soft fines create a
                                   smooth, blurred outline, while solid lines create a sharp, crisp outline.
                                   Trace Contour: It traces image elements using a 16-color palette. Users can set threshold level
                                   and edge type.

                                   Creative Effects

                                   Crafts: It replaces image colors with puzzle pieces, gears, marbles, candy, ceramic tiles, or poker
                                   chips.
                                   Crystallize: It transforms images into crystal formations creating a geometric pixilation of
                                   images in polygon forms.

                                   Fabric:  It reconstructs images by sampling main image colours and replacing them with
                                   needlepoint stitches, quilt patches, rug hooking, strings, ribbons, or a tissue collage.
                                   Frame:  It applies irregular vignette borders to objects or images, resulting in a specified
                                   background colour or transparency. It eliminates the need for extensive masking.
