ViTrace

ViTrace performs raster-to-vector transformation in a real-time. It can generate 2 type of frames - raster (TV-Like) frames and vector frames generated by very fast outline tracing algorithm.
There was implemented 2 types of raster frames - uni-directional, and bi-directional. For vector frames was implemented one algorithm - outline which include various styles (raster filters), that give different results.

Styles.

There are 3 types of styles
Mono - source image transformed to grayscale image. Grayscale image will be converted to 4 colors by means of 3 separation levels. There is ability to select number of separation levels from 1 to 3.
RGB - in this style ViTrace will perform independent calculations for each color channel. Every color channels to be separated to 4 levels, that give up to 64 colors. This allow recover much more detailed tracing than simple back&white
Delta - this style allow to detect contours of figures by changing of contrast levels

Color output

By default ViTrace take colors from original videoframe, but there is ability to generate single color output.

Noise suppression.

For decreasing of noise effect there was implemented fast version of "blur" filter. This filter can be used with all types of algorithms.

Blanking jumps optimization.

ViTrace perform optimization of blanking jumps and that allow to generate more qualitative frames.

Auto Levels.

ViTrace can perform auto-detection of separation levels. For making this feature ViTrace perform analysis of every frame and detect the recessions of color usage. Levels detector can work in Mono and RGB modes.

Output & hardware

New feature of ViTrace - output to Pangolin QM2000 board which come with Pangolin Lasershow Designer 2000. There is ability to work with single frame of QM2000 memory, or store sequence of captured frames directly to memory of QM2000 board.
Output to file, monitor (on screen preview) or LAStudio F4 controller can be performed also.

Source image resolution.

ViTrace allow to trace videoframe with different resolution, start from 80x60 and up to 320x200. Recommended resolution is 160x120. Supported color formats are 16 bit, 24 bit and 32 bit per pixel. Primary ViTrace work with 24 bit per pixel resolution, because this resolution is more preferred.

Frame Rate.

Maximal number of traced frames per second depend on TV system used in your country and and we suggest that the number cant be more that 30. Primary the tracing speed depend on size of input image. ViTrace show 25 frames per second on 500Mhz processor (25% of usage by system monitor) at 160x120 pixels source image size.
