Patent number: 10089540Abstract: A vision system for a vehicle includes a camera having an image sensor and a lens, with the lens exposed to the environment exterior the vehicle. An image processor is operable to process multiple frames of image data captured by the camera and processes captured image data to detect a blob in a frame of captured image data. Responsive to processing a first frame of captured image data, and responsive to the image processor determining a first threshold likelihood that a detected blob is indicative of a contaminant, the image processor adjusts processing when processing subsequent frames of captured image data. Responsive to the image processor determining a second threshold likelihood that the detected blob is indicative of a contaminant when processing subsequent frames of captured image data, the image processor determines that the detected blob is representative of a contaminant at the lens of the camera.Type: GrantFiled: September 12, 2016Date of Patent: October 2, 2018Assignee: MAGNA ELECTRONICS INC.Inventors: Benjamin May, Uwe May

Patent number: 10080032Abstract: Blurriness in a video image transmitted over a lossy network can be reduced by filtering the decoder output to determine whether updating of the reference frame based on the current video data is indicated. An update may be appropriate if the decoder output is sharper than the contents of the display buffer after the last update. Additionally, an update may be appropriate if there was a significant change to the underlying image, and thus to the encoder's input. Whether such a change has occurred can be determined by analyzing the prediction mode, motion vectors, and pixel data of the output image.Type: GrantFiled: May 22, 2017Date of Patent: September 18, 2018Assignee: Polycom, Inc.Inventor: Edmund Thompson
