Patent number: 9819880Abstract: Various techniques are provided for systems and methods to process images to reduce consumption of an available output dynamic range by the sky in images. For example, according to one or more embodiments of the disclosure, a region or area in images that may correspond to the sky may be identified based on the location of the horizon in the images. A distribution of irradiance levels in the identified sky region may be analyzed to determine a dynamic range attributable to the sky region. A transfer function that compresses the dynamic range attributable to the sky region may be generated and applied so that the sky in the images may be suppressed, thereby advantageously preserving more dynamic range for terrestrial objects and other objects of interest in the images.Type: GrantFiled: December 20, 2013Date of Patent: November 14, 2017Assignee: FLIR Systems, Inc.Inventors: Nicholas Högasten, Mark Nussmeier, Eric A.

Patent number: 9602838Abstract: A system and method for correcting artifacts present in video frames is disclosed. The system includes a decision module (110) and an artifact correction unit (120). The system receives artifact metrics (112) and artifact maps (122) corresponding to artifacts present in video frames and prioritizes the video frames to be corrected by considering the type and severity of the artifacts and the content of the video frames (113). Subsequent to prioritizing the video frames, the system corrects artifacts of selected frames by adjusting compressed domain parameters (126), such as quantization parameters and mode decisions. An encoder (130) compresses the video frames according to the adjusted compressed domain parameter to automatically provide a video stream with a lower incidence and severity of artifacts.Type: GrantFiled: December 5, 2007Date of Patent: March 21, 2017Assignee: Thomson LicensingInventors: Gokce Dane, Wuttipong Kumwilaisak, Cristina Gomila

Patent number: 9510005Abstract: The present invention relates to a method of encoding blocks of values, e.g. DCT blocks, generated in accordance with an image compression scheme. The values are expressed as a set of bit planes, each bit plane comprising, for the values, all bits with a specific significance. In each bit plane at least one parameter is determined (7) in accordance with a predetermined definition, the parameter defining a partition of the bits in the bit plane which encloses all set bits. All bits in the partition are transferred (8) to a bit stream that may be truncated. This provides a method with low complexity. The invention further relates to a corresponding encoding device, a corresponding decoding device, and a corresponding bit-stream.Type: GrantFiled: April 28, 2005Date of Patent: November 29, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Renatus Josephus Van Der Vleuten, Lambertus Antonius Van Eggelen, Ihor Kirenko
