The Basic Steps of Pac-n-Zoom® Technology

1. Open the file: [ more]
2. Segment the image: [ more]
3. Save the file: [ more]

1. Input File: The input file is a raster file that needs to be converted to a file type that Pac-n-Zoom will accept. A higher density will produce better results without significantly changing the final file size.

2. Color Segmentation: Regardless of the device that is used to capture the data, the noise will prevent processing. Segmentation mush be run before shape grouping (a.k.a., blob compressor). The first step towards reducing the noise is to group the color together. Humans do this inside their head. For example, if we can not see which dots belong to the animal or forest, the animal will be camouflaged.

Pac-n-Zoom offers 2 types of color grouping (a.k.a., color segmentation). Threshold segmentation (Pull-Down Menu: Noise->Threshold Segmentation) is recommended for use with Pac-n-Zoom Pre.Vu. Edge detection segmentation (Pull-Down Menu: Noise->Edge Detection Segmentation) is recommended for use with Pac-n-Zoom Color.

For the best results, take the default segmentation settings.

3. Shape Grouping: Shape grouping helps to eliminate noise in the image. After both color and shape grouping have completed, most of the noise will have been removed from the image. To be effective, shape grouping must run on a segmented image. Before shape grouping is ran, you may want to set the shape grouping parameters (Pull-Down Menu: Noise->Blob Compressor Parameters). An acceptable tolerance of 2 or 3 is a reasonable value. Shape grouping is ran when the file is saved as a *.pnz file. For golden and debug files, shape grouping is ran when a *.pnh file is saved.
