Abstract: A method for recognizing an action of at least one object in a plurality of images, includes obtaining a plurality of image frames by capturing at least one object on a ground plane; detecting a motion of the at least one object and a motion of the ground plane in each of the plurality of image frames; estimating a trajectory of the ground plane by tracking the motion of the ground plane; correcting the motion of the at least one object in each of the plurality of image frames based on the trajectory of the ground plane; and recognizing an action of the at least one object based on the corrected motion of the at least one object.

Abstract: Provided are a system and a method for recognizing non-line-of-sight human action, the method including receiving a plurality of image frames in a sequential order from an imaging device, wherein at least one of the plurality of image frames comprises at least one entity performing an action; identifying, based on the plurality of image frames, that a first partial portion of the action occurs within a field of view of the imaging device and a second partial portion of the action occurs outside the field of view of the imaging device; identifying a type of a motion which occurs during the action based on the first partial portion; extrapolating the motion based on the first partial portion, and generating a trajectory of the motion corresponding to the second partial portion of the action; and recognizing the human action from the type of the motion and the trajectory of the motion.

Abstract: A method performed by an electronic device for estimating a landmark point of a body part of subject by electronic device is provided. The method includes generating, by the electronic device, an initial coarse estimation of the landmark point of the body part using a light-weight deep neural network, determining, by the electronic device, an occluded region of the body part based on the generated initial coarse estimation of the landmark point using a segmentation mask, estimating, by the electronic device, the occlusion probability for the landmark point in the at least one occluded region and the generated initial coarse estimation, determining, by the electronic device, a correction factor for applying on the generated initial coarse estimation as a measure of the estimated occlusion probability, and selecting, by the electronic device, a pre-defined number of neural networks by applying the determined correction factor for processing the at least one occluded region and the generated initial coarse estimation to generate final estimation of the landmark point.

Abstract: There is provided a method and apparatus for performing gesture recognition in an electronic device, including: tracking a visible trajectory of a hand of a user from a plurality of frames captured by the electronic device, identifying, by the electronic device, a first frame where the hand of the user has gone out of a Field of View (FOV) of the electronic device, identifying the second frame where the hand of the user has come back into the FOV, predicting, using an Artificial Intelligence (AI) model, a trajectory of the hand of the user using one or more frames captured before the first frame, and one or more frames captured after the second frame, and recognizing at least one hand gesture performed during the visible trajectory of the hand of the user, and the predicted trajectory of the hand of the user.

Abstract: There is provided a method and electronic device for generating high resolution peak action frame. The method includes receiving a low resolution (LR) image stream with high frame speed and a high resolution (HR) image stream with low frame speed and detecting at least one pose of at least one human in the LR image stream. The method further includes obtaining a LR peak action frame in the LR image stream based on the at least one pose and identifying a close HR frame from the HR image stream which is closest to the LR peak action frame. The method further includes fetching the close HR frame from the HR image stream which is closest to the obtained LR peak action frame or generating a HR peak action frame by blending the identified HR frame and the LR peak action frame.
