Abstract: The present disclosure provides an image processing method. The method includes reading R rows of data of the image into a first storage buffer, R is an integer greater than 1; upsampling and filtering the R rows of data to obtain M rows of processed data, M is the upsampling multiple in the upsampling and filtering process, and M is an integer greater than 1. The method further includes reading a next row of data of the image into the first storage buffer after processing the R rows of data, the next row of data and the original R−1 rows of data in the first storage buffer are used as the R rows of data for the next upsampling and filtering process; and outputting the M rows of processed data.

Abstract: Described herein are systems, methods, storage media, and computer programs for tracking a plurality of feature points in a first image and a second image. In one embodiment, a first layer of a first image pyramid for the first image and a first layer of a second image pyramid for the second image are obtained. Based on expected pixel locations of the plurality of feature points in the first layer of the second image pyramid, a feature point is selected from the plurality of feature points. For the feature point, a first pixel in the first layer of the first image pyramid is determined, and a second pixel in the first layer of the second image pyramid is determined, where the first pixel substantially matches the second pixel.

Abstract: A method for processing video data of an environment includes, with aid of one or more processors individually or collectively, obtaining in or near real-time a reference position of an imaging device located on a movable object based on one or more previously traversed positions of the imaging device, and modifying an image frame in the video data to obtain a modified image frame based on the reference position of the imaging device and an actual position of the imaging device at which the image frame is taken. The one or more previously traversed positions are obtained using at least one sensor on the movable object. The video data is acquired by the imaging device.

Abstract: Described herein are systems, methods, storage media, and computer programs that support data flow scheduling between processors. In one embodiment, a processor for processing data is disclosed. The processor comprises a flow classifier and a first set of circuits. The flow classifier is configured to assign a flow identifier to a data flow. The first set of circuits is configured to process a plurality of data blocks of the data flow and determine whether to provide information on the processing of the plurality of data blocks to another processor based on the flow identifier.

Abstract: Apparatus and methods for image processing are provided. Imaging devices may be coupled to movable objects, such as unmanned aerial vehicles (UAVs). One or more images may be captured by an imaging device, such as a camera. The one or more images may be captured under the same or different parameters. The one or more captured images may be processed for use in computer vision applications. Processing the one or more captured images may involve analyzing a texture of the images. Subsequent images may be captured under the same or different parameters.
