Abstract

We developed an algorithm to search automatically for LSB galaxies in the DPOSS plate scans. The algorithm consists of three different steps in which: i) the original image is processed with a standard image analysis package (e.g. SExtractor) and normal high surface brightness objects are removed; ii) a series of filters with an exponential compensated profile are applied at different scales; iii) significance maps are pruned by selecting, for each detection, the characteristic scale and significance; iv) candidates are then trimmed by measuring them on the original image with a fit with an exponential profile. Multicolor optical follow-up with CCD has begun on some of the best candidates.
