Heart Sound Classification (PCG) — TensorFlow + FastAPI; live demo on HF Spaces

A toolkit for BLE digital stethoscopes — capture, DSP, log-mel spectrograms, and murmur classification on the Apple Neural Engine

Final year capstone project for heart disease detection using a multi-modal approach. We trained separate ML models on ECG, PCG, and PPG signals and fused their confidence scores using a mathematical method to provide a more accurate and holistic risk assessment. Project Members: Anandakrishnan A and Aryan Matte

Phonocardiogram (PCG) signal processing and analysis for Internet of Medical Things (IoMT) applications, including filtering, heart sound visualization, and feature extraction.

The main objective of this project is to design and implement an automatic classification method, CNN, to classify cardiovascular diseases (CVDs). Diseases covered include Mitral Stenosis (MS), Aortic Stenosis (AS), Mitral Regurgitation (MR), Mitral Valve Prolapse (MVP), along with normal heart sound.

Exploratory computational framework for modeling cardiac acoustic signals as latent physiological topology using manifold learning, trajectory dynamics, anomaly detection, and cyclic state-space analysis.

🫀 Screening for cardiac pathology from smartphone phonocardiograms. A research pipeline and its findings: data-centric methodology, the CardioNet architecture family, real metrics, and honest limitations. Research prototype, not a medical device.

Non-Invasive Valvular Disorder Screening from Phonocardiograms. Upload any digital stethoscope PCG recording (WAV, MP3, M4A, FLAC, OGG) or select a clinical reference sample to analyze cardiac cycles for murmurs across 5 pathology classes.

This project builds a deep-learning-based heartbeat sound classification system using MFCC features and multiple models including CNN, BiLSTM, and a Hybrid CNN–BiLSTM architecture. The system detects and classifies heart sounds into normal, murmur, and artifact categories, supporting early cardiac abnormality detection.

A Streamlit app for CWT & FFT signal analysis with PCG feature detection, built entirely from scratch.

Optimization of CNN, GRU, and CNN-GRU models for compressed PCG classification with deployment on STMicroelectronics boards, including the Neural-ART accelerator.

FPGA design for extracting PSD, Hilbert, Wavelet, and Homomorphic envelograms from phonocardiogram (PCG) recordings.

Myocardial infarction detection from phonocardiogram (PCG) heart sounds using a hybrid CNN-LSTM model, with a Flask web interface. 560 recordings from 140 subjects, collected at Hasan Sadikin Hospital, Indonesia.
