A data compression technique for MWD applications uses feature detection, extraction, followed by image compression for only the region(s) of interest. The detection approach processes data in real time. It triggers on the start and end of a feature without processing any further features. This provides...http://www.google.co.uk/patents/US7424365?utm_source=gb-gplus-sharePatent US7424365 - Apparent dip angle calculation and image compression based on region of interest
