Title: Survey coverage parameters
Inventor: BENGT BOBERG
IPC: G01V3/12
Filed: 2016-01-08
Abstract: A method of seismic or electromagnetic geophysical surveying comprises accessing 410 information obtained during a previous pass by a survey vessel including information about unique fold for a plurality of bins, where unique fold is the number of hits in a given bin that are unique according to a differentiation criteria e.g. different offsets or azimuths. For a subsequent pass an added unique fold parameter is determined 420 for one or more bins and the position of one or more elements of a survey system is adjusted 430 based on the added unique fold. A ratio of the determined added unique fold to a theoretically obtainable added unique fold may be determined, and the adjustment may be based on this ratio. Survey elements may be steered to increase added unique fold without leaving coverage holes that violate an acceptability criterion. Steering may performed automatically. Coverage parameters may be graphically displayed to an operator.

Title: Method and system for detecting that an object of interest has re-entered a field of view of an imaging device
Inventor: JAYANT KUMAR
IPC: H04N5/222
Filed: 2016-01-25
Abstract: A system and method for processing a sequence of images from an image sensor to identify and re-identify an object of interest in the sequence. The object is detected 502 in a first image and positional parameters that correspond to the object in the first image are determined 503 using a motion sensor. A range of positional parameters within which the object may appear in a field of view (FOV) are determined 504. When it is detected 505 that the object has exited the view field motion sensor data and the positional parameters are used to determine 508 when the object has likely moved back into the field of view. The current frame is then analysed to confirm 509 that the object has re-entered the field of view. A predicted re-entry location of the object may be determined and confirmation that the object has returned may comprise analysing the predicted location. The object may be tracked while it is in the field of view and a marker may be overlaid on the image to highlight the location of the object.

Title: Compression of 360 degree content
Inventor: Albert Saá-Garriga
IPC: G06T9/00
Filed: 2017-10-12
Abstract: Apparatus and methods are disclosed for compressing 360 degree content which comprises at least one 360 degree image or video. A rotation is applied to the 360 degree image such that a compression ratio achieved when the 360 degree content including the rotated 360 degree image is compressed is increased, relative to a compression ratio that would be achieved when compressing the as-received 360 degree content. The 360 degree content including the rotated 360 degree image can then be compressed using the compression algorithm, and outputted together with a rotation parameter which defines the applied rotation. When reproducing the compressed 360 degree content, an inverse rotation can be applied before the 36o degree image is displayed. The rotation to be applied may be determined by evaluating a plurality of candidate rotations and selecting the one that provides the best compression ratio, on the basis of a rotation previously applied to one or more frames of 360 degree video or on image or line analysis. The candidate rotations may be selected on a random basis or the image analysis may identify a region of low complexity in the image and the candidate rotations will be chosen to place this region in a predetermined area or the line analysis may determine a representative line orientation in the image and a candidate rotations selected to bring the representative line direction closer to a predetermined direction. The candidate rotations may also be determined by use of a neural network trained on 360 degree content and the respective determined rotations.
