Title: Methods and devices for linear component sample prediction using a double classification
Inventor: CHRISTOPHE GISQUET
IPC: H04N19/50
Filed: 2018-02-23
Abstract: Determining samples of a block in an image comprises obtaining pairs of samples 1005 in a first and second image component located in the neighbourhood of the block. The sample pairs are associated with bins 1006 according to with least a property of the sample pairs and bins are associated 1009 with groups of samples in the block. For each group of samples in the block a parameter is determined 1010 based on the sample pairs associated with the bins associated with the group. Samples of the block in the first image component are determined 1016 from samples of the block in the second image component based on the parameter determined for the group the samples belong to. The first image component may be a chroma component and the second image component may be a luma component. The samples may be determined during image encoding or decoding for example to predict chroma components from luma components. The samples may be determined using a linear model the parameters of which are determined from pairs of neighboring pixels. The groups of pairs may be associated with the sets in the block in a many to many way.

A state defining circuit, 118 and poc, may be configured to set the level shifter output to a defined state when the supply voltage Vdd of the first domain is absent. Having the n-wells of all the PMOS transistors at the same potential may reduce the footprint in the IC by eliminating n-well spacing.

The terminal device prompts the user to place the container storing the article onto a weighing scale which is associated with a weighing scale identifier code retrieved from a second look-up table. The weight measurement value is used to determine the combined weight of the container and the article and subsequently the weight of the article is determined from difference between the weight of the container and the combined weight of container and the article. Also claimed is a method for determining the weight of an article by making two measurement on the scale (e.g. weighing the container first and then weighing the article and container). Another claim relates to determining via weighing whether a user has removed an unpurchased article from an area at an exit point.
