Abstract: According to a first aspect of the present invention, there is provided a method for objectively determining a frailty score for a subject, the method comprising: deriving an attribute from sensor data including at least one of EMG data and motion data of the subject and obtained from at least one limb of the subject; quantitatively processing the attribute to determine how the subject is responding to the rehabilitation or exercises program; and objectively determining the frailty score based on the quantitative processing.

Abstract: Systems and methods predict functional and cognitive recovery of a person after the person has experienced a brain injury such as traumatic brain injury, cerebrovascular disease, and stroke. A computer system includes a database that stores multimodal data of the person recovering from a brain injury and a computer that analyzes the multimodal data over multiple intervals that span several months of time. The computer executes longitudinal heterogeneous trajectory analysis on the multimodal data and executes separation of heterogeneous groups that include good recovery potential of the brain injury, moderate recovery potential of the brain injury, and poor recovery potential of the brain injury. Based on the longitudinal heterogeneous trajectory analysis and the separation of the heterogeneous groups, the computer predicts functional recovery of the person from the brain injury.

Abstract: The present disclosure provides a method and an apparatus for estimating a body part position of a person, the method comprising: detecting, by a processor, a plurality of body part positions of the person from an image in which the person is detected, wherein each of the plurality of body part positions corresponds to a body part of the person; and estimating, by the processor, a body part position of the person based on the detected plurality of body part positions.

Abstract: A device and method for model estimation may be provided. The device (100) comprises a local model setting unit (106) configured to determine a function in response to receiving an input relating to a local model, the function corresponding to the local model; and a local model optimization unit (114) configured to optimize a parameter for model estimation based on a refined regularization term of the local model, the refined regularization term being refined by shape information of the local model relating to the received input so as to optimize the parameter for model estimation.

Abstract: The present disclosure provides a method and an apparatus for estimating a rotation angle of a head of a person using an image comprising a frontal view of the person, the method comprising: calculating a distance between two or more vertically apart points on the head of the person from the image; and estimating a rotation angle of the head of the person based on the distance.

Abstract: The present disclosure provides a method and an apparatus for identifying a posture condition of a person, the method comprising: detecting a rotation of one or more body parts of the person around an upright center axis of the person; and calculating an asymmetric score of the one or more body parts based on the rotation of the one or more body parts of the person, the asymmetric score relating to a level of the posture condition of the person.
