Abstract: Methods and systems for mobile device-based touchless control can include receiving an image of a user and applying a convolutional neural network to the image to determine a feature map. Further, a key-points map and an affinity-field map can be determined based on the feature map, and the pose of the user can be determined based on the maps. The methods and system further include identifying an activation gesture of the user and determining a validity of a bounding box associated with the pose of the user, and tracking the pose of the user and a portion of a body of the user for performing the touchless control. Further, the methods and systems include determining a mapping between the portion of the user's body and a cursor position associated with an application, and moving the cursor position to enable touchless user interaction. Embodiments use computer vision techniques to enable a resource-limited mobile device to conduct the aforementioned steps.

The methods and systems perform the steps of capturing a training video of a player using a camera on the mobile device; augmenting the training video with a visual cue for a cue period starting from a first time instant; determining whether the player has responded to the visual cue at a second time instant within the cue period, by analyzing a body posture flow of the player between the first time instant and the second time instant, wherein the body posture flow is extracted from the training video by performing a computer vision algorithm on one or more frames of the training video; and in response to determining that the player has responded to the visual cue, generating a feedback to the player.

Abstract: Methods and systems for ball shot attempt detection and game analytics generation are disclosed. The methods and systems perform steps to receive an input video of a ball gameplay, wherein the input video was captured using a stationary camera, and wherein frames of the input video comprises a goal; identify a Region of Interest (ROI) surrounding the goal by performing a first computer vision algorithm on the input video; detect a ball within the ROI during a shot attempt and determining a trajectory of the ball by performing a second computer vision algorithm on the input video; and identify a player relevant to the shot attempt based on the trajectory of the ball. In some embodiments, the computer vision algorithms comprise a convolution neural network (CNN). The present invention uses computer vision techniques to enable a resource-limited mobile device such as a smartphone to efficiently execute the new process.

Abstract: A platform for transferring business is described. Users use registration logic to open accounts. A first user submits a business with a unique identifier. Second, third and further users bid on the business using bidding logic and a winning bid normally corresponds with a bid for a higher profit sharing percentage to share with the first user. When a benefit is registered in favor of a winning bidder, the benefit is divided between the winning bidder, the first user and an operator of the platform.

Abstract: Interactive system for responding to conditions after an answering machine has been detected in an automatic telephone number dialing and announcing system so that realistic sounding recorded messages can be delivered without truncation. The system starts by: placing a telephone call to an answering machine; playing a recorded message onto the answering machine: monitoring the machine for echo cancellation sounds (sounds emanating from the answering machine) while simultaneously playing the message; repeating the playing of said message onto the answering machine while monitoring for echo cancellation sounds; and continuing to play the message until there are no echo cancellation sounds whereby the recorded message is launched unto the answering machine and continues playing the message to completion. If there are greater than three occurrences of echo cancellation sounds.
