Title: Low-latency channel equalization using a secondary channel
Inventor: Kevin J Babich
IPC: H04L25/03
Filed: 2019-11-14
Abstract: An equalization method has been developed for low latency, low bandwidth wireless communication channel environments. With this method, an exact copy, nearly exact copy, or some facsimile of a message (or associated information), which was transmitted via a low latency, low bandwidth wireless communication channel, is also sent via a backend communication channel such as a fiber optic network. Equalization is generally performed by comparing the originally received message to the copy sent via the backend channel. The original message can incorporate an added channel delay to compensate for the time delay between the primary wireless channel and the backend channel.

The distance map comprises a distance to a lesion contour for each voxel of the given two-dimensional slice. The mechanism performs local maxima identification to select a set of local maxima from the distance map such that each local maximum has a value greater than its immediate neighbour points. The mechanism performs seed relabelling based on the distance map and the set of local maxima to generate a set of seeds. Each seed represents a centre of a distinct component of a lesion contour. The mechanism performs image segmentation on the lesion mask based on the set of seeds to form a split lesion mask.

Title: Image data compression
Inventor: Ilaria Martinelli
IPC: G06T9/00
Filed: 2022-12-07
Abstract: Compressing a block of image data comprising image element values, each comprising a plurality of data values relating to a reference channel and a plurality of non-reference channels. For the non-reference channels a number of bits for a non-channel decorrelating mode is determined for losslessly representing the difference between the maximum and minimum data values for the block. Decorrelated data values are determined by finding, for each image element value in the block, a difference between the data value of the non-reference channel and the data value of the reference channel. A number of bits for a channel decorrelating mode, is determined for losslessly representing a difference between the maximum and minimum of the decorrelated data values of the non-reference channel for the block. The determined number of bits for the non-channel and channel decorrelating modes are compared and one mode selected based on the comparison. If the channel decorrelating mode is selected, the decorrelated data values for the non-reference channel for the block are used for determining compressed channel data for the non-reference channel. For each channel, compressed channel is determined and final compressed data formed comprising the selected mode for each non-reference channel and the compressed channel data.
