Deep Learning Model for Posture-based Height Estimation of Toddlers on Monocular Images
Stunting, a chronic nutritional problem that inhibits the growth and development of children under five, requires early detection through accurate height monitoring. Existing manual measurement methods are often inaccurate and impractical in active toddlers. This research proposes a non-contact toddler height estimation model based on computer vision and deep learning using monocular images. The proposed architecture integrates Mask R-CNN (via Detectron2) for precision instance segmentation, MediaPipe Pose for 3D pose keypoint estimation and bounding box adjustment, and DenseNet121 as the main backbone for feature extraction and height prediction via regression approach. The model was trained using transfer learning and fine-tuning techniques on a dataset of personal toddler images rich in pose variations and lighting conditions. Comprehensive image pre-processing, including exposure adjustment, denoising, sharpening, background removal, and resizing, is performed to improve the quality of the input data. Model performance was evaluated using standard regression metrics such as Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), and tolerance-based accuracy (±5 cm). This integration aims to improve the accuracy and robustness of toddler height prediction from a single image, offering a more efficient and non-invasive stunting detection solution.
Model Deep Learning untuk Estimasi Tinggi Balita Berdasarkan Postur pada Gambar Monokuler
Stunting, masalah gizi kronis yang menghambat pertumbuhan dan perkembangan balita, memerlukan deteksi dini melalui pemantauan tinggi badan yang akurat. Metode pengukuran manual yang ada saat ini sering kali tidak akurat dan tidak praktis pada balita yang aktif. Penelitian ini mengusulkan model estimasi tinggi balita non-kontak berbasis computer vision dan deep learning menggunakan gambar monokuler. Arsitektur yang diusulkan mengintegrasikan Mask R-CNN (melalui Detectron2) untuk segmentasi instans presisi, MediaPipe Pose untuk estimasi titik pose 3D dan penyesuaian bounding box, serta DenseNet121 sebagai backbone utama untuk ekstraksi fitur dan prediksi tinggi melalui pendekatan regresi. Model dilatih menggunakan teknik transfer learning dan fine-tuning pada dataset gambar balita pribadi dengan variasi pose dan pencahayaan yang kaya. Pengolahan citra komprehensif, termasuk penyesuaian eksposur, pengurangan derau, penajaman, penghapusan latar belakang, dan pengubahan ukuran, dilakukan untuk meningkatkan kualitas data input. Performa model dievaluasi menggunakan metrik regresi standar seperti Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), dan akurasi berbasis toleransi (±5 cm). Integrasi ini bertujuan untuk meningkatkan akurasi dan ketahanan prediksi tinggi balita dari satu gambar tunggal, menawarkan solusi deteksi stunting yang lebih efisien dan non-invasif.
