Abstract

fetched live from OpenAlex

Gesture recognition has become increasingly popular, in response to the growing demand for intelligent and personalized human-computer interaction (HCI) and human-to-human interaction. However, gesture recognition raises a high requirement on the background color of the gesture image, and faces difficulty in extracting multiple gesture features. To solve these problems, this paper presents a novel approach for gesture feature extraction and recognition based on image processing. Firstly, the workflow of the proposed gesture recognition method was given, and a series of preprocessing was performed on the original gesture image, prior to formal extraction and recognition. Next, the authors detailed the extraction of features from gesture boundaries and fingertips. Finally, a convolutional neural network (CNN) was constructed for gesture recognition, and a gesture recognition model was developed based on residual network. The proposed approach was proved to be valid through experiments. The research results provide a reference for the application of CNN in the recognition of various postures or shapes.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
