Embodiments relate to a system, computer program product, and method for determining shelter areas for two-wheeler vehicles, and, more specifically, for dynamically distinguishing the behavior of two-wheeler vehicles and non-two-wheeler vehicles as an indicator of shelter areas from inclement weather. The behavior of the vehicles is distinguished through a plurality of two-wheeler vehicles slowing down and congregating at a particular location as a shelter against inclement weather, while non-two-wheeler vehicles may slow down, however, not stop proximate this location.

An object detection algorithm is selectively applied to frames in a video. A frame in the video is analyzed using a set of neural networks of the object detection algorithm to detect a location of an object in the frame and predict a bounding box for the object in the frame. A magnitude of a delta between the frame and a second frame is determined. The magnitude of the delta is determined based on a difference between the two frames in values of at least one parameter of their respective sets of pixels. Responsive to the magnitude of the delta being less than a threshold, a new bounding box is predicted for the object in the second frame without analyzing the second frame using the set of neural networks.

Non-resource-intensive object detection

Machine learning based video compression

A method, and associated computer system and computer program product, for video compression that includes receiving a video file including a plurality of frames, identifying at least one image feature in each of the plurality of frames, determining a semantic state change of the image feature for each successive frame after a first of the plurality of frames, and storing the first of the plurality of frames and the semantic change of the image feature for each successive frame after the first of the plurality of frames.

Video compression using cognitive semantics object analysis

A processor(s) processes multiple image frames of a scene for object recognition by applying a first process of a plurality of visual recognition processes using different grid sizes, to one or more image frames. The first process divides the image frame(s) into an m&#xd7;m grid to determine bounding boxes for identifying one or more objects. Based on detecting passage of a predefined time interval, less than a period of time represented by the image frames, processing dynamically switches to a second process to process one or more other image frames. The second process is applied to the other image frame(s), dividing the other image frame(s) into an n&#xd7;n grid to determine bounding boxes for identifying one or more other objects in the other image frame(s), where the n&#xd7;n grid used by the second process is different from the m&#xd7;m grid.

Approaches presented herein enable optimization of a developing application to a user base. More specifically, application-centric data is gathered during a cultivation phase of the developing application. Substantially concurrently with the cultivation phase of the developing application, the application-centric data is analyzed according to static code of the developing application, a testing of the developing application, or a user experience (UX) design of the developing application. A machine learning model is applied to the analyzed application-centric data. This machine learning model is trained on historic application feedback data from applications available to the user base. Based on the machine learning model, a recommended change to optimize the developing application to the user base is generated.

Aspects of the present invention provide devices that filter a subset of items from a database according to a model which predicts sales of items in the database with social media data and the subset of items filtered according to a highest predicted sales. The model comprises a machine learning model trained with sales history of items from the database and social media data history. The devices load the filtered subset of items from the database into a data cache, receive a search which searches for one or more items in the database, and return one or more items of the loaded subset of items from the data cache in response to the received search.

Embodiments selectively place or accept telephone calls based on recipient preference information, wherein processors are configured to determine whether a first telephone number of a different telephone numbers associated to an identified recipient is ranked highest relative to others of the telephone numbers within the ordered ranking for preferred use in calling the recipient at a local times and geographic locations of receiving mobile devices associated with the telephone numbers. In response to determining that the first number is not ranked highest, the embodiments stop execution of the initiated call to the first number and request authorization from the caller to place the call to another of the telephone numbers that is ranked highest within the ordered ranking. Embodiments further iteratively request authorization from the caller to place the call to others of the telephone numbers next-highest in rank, until placing the call to an authorized one.
