An Efficient Region-of-Interest Cropping Algorithm to Extract Small Regions of Video Out of Compressed Video Streams

PSU researchers have created a technology which supports fast and efficient region-of-interest cropping from high-resolution video. We have a mechanism to compress a compliant video stream, and still allow cropping.

Nitrogen Dioxide Gas Sensor

PSU researchers have developed a new chemical gas sensor capable of detecting nitrogen dioxide (NO2) at levels less than 100ppb (two orders of magnitude more sensitive than current chemiluminescent based NOx sensors), having a dynamic linear range of parts per million to parts per billion, and a speed of detection of 60-120 seconds. Unlike existing...
