Abstract: Aspects of the present disclosure relate to systems and methods for performing multiple frame electronic image stabilization (EIS). An example device may include a memory and a processor configured to receive a current frame for performing multiple frame EIS, determine a location of a cropping in the current frame for an EIS image, and crop current image information from the current frame using the cropping. The cropped current image information is included in the EIS image. The processor further may be configured to determine a portion of the cropping for the EIS image not in the current frame, retrieve from the memory prior image information for the portion of the cropping from one or more prior frames in response to determining the portion of the cropping not in the current frame, and generate, for the current frame, the EIS image including the current image information and the prior image information.

Abstract: Techniques and systems are provided for generating a background picture. The background picture can be used for coding one or more pictures. For example, a method of generating a background picture includes generating a long-term background model for one or more pixels of a background picture. The long-term background model includes a statistical model for detecting long-term motion of the one or more pixels in a sequence of pictures. The method further includes generating a short-term background model for the one or more pixels of the background picture. The short-term background model detects short-term motion of the one or more pixels between two or more pictures. The method further includes determining a value for the one or more pixels of the background picture using the long-term background model and the short-term background model.

Abstract: An apparatus includes a processor and a memory. The memory stores instructions that when executed by the processor cause the processor to perform operations including receiving a command to perform an image capture of an image including an object. The operations further include determining a first speed threshold based on a first light condition at a first time. The operations further include determining a first speed of the object. The operations further include, in response to determining the first speed of the object exceeds the first speed threshold, determining a second speed threshold based on a second light condition detected at a second time. The operations further include determining a second speed of the object. The operations further include initiating the image capture of the image in response to determining the second speed of the object does not exceed the second speed threshold.

Abstract: Methods and imaging devices are disclosed for determining a first direction to move a lens in an autofocus operation. For example, one method includes capturing a plurality of frames depicting a scene, selecting a portion of at least one frame that corresponds to an object in a displayed frame, and tracking the object in the plurality of frames, where tracking the object provides a reference parameter of the object for each of the plurality of frames. The method may further includes detecting a change in the reference parameter of at least a first frame and a second frame of the plurality of frames, determining a focus direction based on the change in the reference parameter, and initiating a focus operation by moving a lens of the imaging device based on the determined focus direction.

Abstract: A processor-implemented method for detecting and decoding barcodes using an artificial neural network (ANN) includes receiving an image by the ANN. The ANN generates one or more bounding boxes corresponding to one or more barcodes located in the image. The ANN extracts a set of features of the image in a region of each of the one or more bounding boxes. The set of features of the image in the region of the one or more bounding boxes are decoded by the ANN to generate a prediction for each character of the one or more barcodes in the regions of the one or more bounding boxes.
