Abstract: A computer implemented method of data processing comprises receiving an input data stream; identifying, by a first algorithm, one or more first content features of the data stream; determining, based on at least one output of the first algorithm, one or more portions of the data stream to be stored in a first buffer; storing the determined portions in the first buffer; identifying, by a second algorithm, one or more second content features of the data stream using the stored portions of the data stream; and generating, for output to a user, an output based on the identified second content features; wherein the second algorithm is computationally more complex than the first algorithm.

Abstract: A method of identifying fluid retention in a body part of the patient by directly or indirectly measuring a first parameter relating to a size of a body part of the patient to obtain an actual measurement of the body part, obtaining an estimated measurement of said first parameter relating to the size of the body part of the patient by measuring alternative predefined parameters of the patient, wherein said estimated measurement is calculated based on a mathematical relationship between said alternative parameters and the size of the body part; and correlating the actual and estimated measurements of the body part of the patient to assess any fluid retention in the body part.
