Solution Overview
Problem
Existing machine-learning models struggle to accurately detect and label specific moments in videos that correspond to when a human would perceive something of significance, limiting their ability to mirror human behavior and predict reactions.
Innovation Solution
A method involving a machine-learning model trained on videos with labeled frames of perception, which identifies an object-of-interest and detects specified motions within an input video, labeling the frame as the moment of perception.

Engineering Contradiction Analysis
1Reliability
If machine-learning models are trained to detect and label specific moments in videos, then the ability to mirror human behavior and predict reactions is improved, but the complexity of the model training and data processing increases
Solution Approach 1:
The video is divided into discrete frames, and the task is segmented into detecting specific motion types (e.g., walking, running, jumping) in each frame. This segmentation allows the model to process complex video data into manageable units, improving training efficiency and accuracy without overwhelming complexity.
Solution Approach 2:
The system performs preliminary actions by pre-processing video data to identify and extract specific motion patterns before final classification. This includes detecting motion vectors, identifying object trajectories, and preparing labeled datasets in advance, which simplifies the main training process and improves reliability.
2Measurement precision
If the machine-learning model processes video frames to identify moments of perception, then the accuracy of predicting human reactions is improved, but the processing time and computational resources increase
Solution Approach 1:
The system extracts only the critical information from each video frame related to motion detection and human perception moments. By taking out and focusing on key features such as motion vectors, object trajectories, and temporal patterns, the model achieves high precision prediction while reducing unnecessary processing time and computational resources.
Solution Approach 2:
The model applies partial action by processing only the necessary portions of video data required for motion detection, rather than analyzing every pixel and frame in detail. This selective processing maintains prediction accuracy while significantly reducing processing time and computational overhead.

AI summary
Detection of moment of perception is provided. A method includes receiving an input video comprising a plurality of image frames including an object of interest. Based on the plurality of image frames, a motion associated with the object of interest is determined, and the plurality of image frames are classified using a machine-learning model to identify one of the plurality of image frames that indicates a moment of perception of the determined motion.
