This page is not an official page and has a very temporary charasteristic, but one can find some test results here.

The work presented here is connected with the "Pi of the sky" project.

Cuts used by me in algorithms by Marcin Sokolowski (in polish)

Most recent results (a very "temporary version")

"Laplace" tests (26.04.2004), with short, unfinished introduction

The paper (in polish) covers flash recognition, kernel-based algorithm. The kernel (called a Laplace) is a way of couting a single pixel brightness, with use of surrounding pixels. There are many kernel types involved, each defining different pixels to be summed and different to be subtracted. The paper also shows influence of specific cuts on results. All test were done on a single night frames, taken with 768x612 camera, with 2x2 binning.

The paper covers early sag of flash recognition algorithm used in "Pi of the sky" project. It was based on simple analysis of differeces in brightness of pixels between proceeding frames, or between specially defined groups of pixels (called "shapes"). The paper shows influence of different shape types or sizes on algorithm efficiency (and background). It also illustrates some history of new cuts and improvements inroducent into algorithm over the time.
