Evaluation of the Power Consumption of Image Descriptors on Smartphone Platforms
Bibliographic record
Abstract
Important number of applications (APPs) used in smartphones use computer vision techniques that rely on limited battery power devices. Example of such techniques includes object detection algorithms such as HOG-SVM and Lbp-AdaBoost. In this paper, we evaluate the energy consumption of the most common descriptors and classifiers used in the literature. We begin our work by the implementation of the following algorithms: Lbp-AdaBoost, Haar-AdaBoost, HOG-AdaBoost and HOG-SVM on smartphones. Next, we run these algorithms to detect a specific object (for instance large animals). Several experiments are done to measure the energy consumption of each algorithm on two smartphones HTC ONE and Google Nexus 5. The energy consumption is evaluated using an application called PowerTutor. We find that faster detectors consume less energy, and vice versa. For instance, HOG-AdaBoost has the most energy-saving among the detectors used in this paper.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
