    摘要: A method of facilitating obtaining a first signal, for analysis to characterize at least one periodic component, includes obtaining two second signals representative of intensities of electromagnetic radiation. The first signal is at least derivable from an output signal obtainable by applying a transformation to the second signals such that any value of the output signal is based on values from each respective second signal at corresponding points in time. The method further includes obtaining a value of a variable determining influences of components of respective second signals on the output signal when the signals corresponding to the second signals are captured and the transformation is applied, by (i) analyzing the first, second and/or the output signals to select a value of a parameter corresponding to a respective one of the variables; or (ii) calculating values of at least one time-varying factor corresponding to a respective one of the variables.

    摘要: A method of processing a signal including at least a component representative of a periodic phenomenon in a living being includes obtaining a sequence of images showing the living being, extracting at least one first signal having at least a component representative of a periodic phenomenon in a living being from the sequence of images using remote plethysmography. Separate data representative of at least a periodic component of motion of the living being are obtained by carrying out motion analysis of the sequence of images. The data are used at least to suppress a component of the first signal corresponding to the periodic component of motion of the living being. The method is unobtrusive to the living being, and the living being can be in motion.

    摘要: The present invention relates to a device and a method for extracting information from detected characteristic signals. A data stream (26) derivable from electromagnetic radiation (20) emitted or reflected by an object (10) is received. The data stream (26) comprises a continuous or discrete characteristic signal (68) including physiological information (30) indicative of desired object motion to be detected and utilized so as to extract at least one at least partially periodic vital signal of interest. A plurality of characteristic index elements (60) can be derived from the data stream (26) through a dimensional reduction (66). The plurality of characteristic index elements (60) comprises a directional motion component (70) associated with a disturbance-reduced index element (40) having a determined orientation substantially aligned with a reference motion direction (41) indicative of the desired object motion. Consequently, dimensional reduced data can be utilized for detecting the vital signal of interest.
