A Real-time Frame-based Multiple Pitch Estimaiton Method Using the Resonator Time- Frequency Image
In this paper, we describe a new method submitted to the 2007 Music Retrieval Evaluation eXchange (MIREX) Multiple Fundamental Frequency Estimation task. The Resonator Time-Frequency Image (RTFI) is used as the basic time-frequency analysis tool. The method makes a preliminary pitch estimation by a simple peak-picking operation in the pitch energy spectrum, which is produced from the original e...

An automatic Number Plate Recognition (ANPR) is a popular topic in the field of image processing and is considered from different aspects, since early 90s. There are many challenges in this field, including; fast moving vehicles, different viewing angles and different distances from camera, complex and unpredictable backgrounds, poor quality images, existence of multiple plates in the scene, va...
متن کاملPitch Estimation Based on Long Frame Harmonic Model and Short Frame Average Correlation Coefficient
We propose a pitch estimation method based on long frame harmonic model (LFHM) and short frame average correlation coefficient (SFACC). The long frame used here is three times as long as the short frame. Our approach consists of two main steps: pitch candidates extraction based on LFHM, and final pitch selection based on the SFACC. The long frame analysis for speech signal is able to achieve a ...
متن کاملNovel speech duration modifier for packet based communication system
In this paper, we propose a real-time method for duration modification of speech for packet based communication system. While there is rich literature available on duration modification, it fails to clearly address the issues in real-time implementation of the same. Most of the duration modification methods rely on accurate estimation of pitch marks, which is not feasible in a real-time scenari...
متن کاملNeural Network Performance Analysis for Real Time Hand Gesture Tracking Based on Hu Moment and Hybrid Features
This paper presents a comparison study between the multilayer perceptron (MLP) and radial basis function (RBF) neural networks with supervised learning and back propagation algorithm to track hand gestures. Both networks have two output classes which are hand and face. Skin is detected by a regional based algorithm in the image, and then networks are applied on video sequences frame by frame in...
