SegmentDisplayOCR is a seven-segment display recognition filter for AviSynth. It has built in logging functionality (it will log frame recognition results) and also can be used in AviSynth conditional filters. The main purpose of this filter is to process readings of various digital instruments (e.g. digital multimeters) captured on video. So if your favourite instrument lacks interface for connecting it to PC you can capture it's readings on cam and convert them to computer readable format with SegmentDisplayOCR filter.
