Geo Semi targets auto, cloud markets with video analytics

Geo Semiconductor is hoping to further grow its video processor business as it aims for the automotive and cloud-based consumer markets. Geo plans to incorporate smart video analytics into its eWarp video processors and produce smarter heads-up displays (HUDs) for car windshields and smarter video-monitoring solutions for home-security.

The first mass market application for which Geo Semi has already crafted sophisticated video analytics are HUDs for automobiles. Video analytic software for HUDs today must segment the tasks into separate operations, including de-warping the image from a 180 degree camera, adding the tactical overlay information to outline the road and call-out obstacles, then rewarp the image for projection on the curved surface of the car's windshieldall in real time. In addition, before the car can be shipped from the manufacturing plant, its cameras must be painstakingly calibrated for the particular orientation and curvature of each type of car using labour-intensive manual techniques.

To solve this problem, Geo Semi's video analytics combines all these separate automotive operations into a single complex polynomial that can be calculated in real time using its eWarp processor, resulting in a much less expensive solution that is faster and requires no manual calibration steps.

The second area for which Geo Semi has crafted complex analytics to solve multi-step video processing into a single real-time operation is home security. There Geo Semi has made complex video processing steps into simple drag-and-drop operations that consumers can perform themselves on a smartphone. For instance, consumers can define a region where their home monitor activates, such as guarding glass door entries at waist-high and above without sounding alarm when dog walks by at floor level (see photo). In operation, the video processing steps are integrated with both the smartphone and cloud-based access and storage options.
