چکیده
This paper illustrates the development of a system to measure the variation in yarn parameters using image processing with the help of a low cost USB web camera along with a yarn moving arrangement. The complete system comprises of yarn guides and tension control device, motor with gear box, monitor for displaying yarn parameters etc. The system enables to develop yarn diameter spectrogram and neps count present in the yarn in a single unit. The performance of the developed system is free from any fluctuation of ambient temperature or humidity. The available results are verified with that available from a powerful microscope. Results are available on the monitor showing diameter spectrogram calculated for a specific length of the yarn, counters displaying the number of neps available in that yarn for that specific length. The future goal of this work is to acquire the image of the yarn from a spinning frame with the help of a high resolution web camera and to process the same with advanced software to characterize the yarn which in turn dictates the fabric appearance.

Yarn Hairiness Determination Using Image Processing
Yarn hairiness is one of the key parameters influencing the quality of yarn.It is observed that yarn quality has been deduced based on yarn length and diameter only. But these parameters do not provide much information about yarn quality. Thus it is proposed to derive more yarn quality parameters like yarn hairiness, uniformity of yarn and its thickness. In textile industry, image processing is...
متن کاملClassification of emotional speech using spectral pattern features
Speech Emotion Recognition (SER) is a new and challenging research area with a wide range of applications in man-machine interactions. The aim of a SER system is to recognize human emotion by analyzing the acoustics of speech sound. In this study, we propose Spectral Pattern features (SPs) and Harmonic Energy features (HEs) for emotion recognition. These features extracted from the spectrogram ...

متن کاملCipher text only attack on speech time scrambling systems using correction of audio spectrogram
Recently permutation multimedia ciphers were broken in a chosen-plaintext scenario. That attack models a very resourceful adversary which may not always be the case. To show insecurity of these ciphers, we present a cipher-text only attack on speech permutation ciphers. We show inherent redundancies of speech can pave the path for a successful cipher-text only attack. To that end, regularities ...
متن کاملIdentification of Yarn Periodical Errors Using Signal Processing Techniques Based on Capacitive and Optical Sensors Measurements
This paper presents a study to identify the type and location of yarn periodical errors applying three different signal processing approaches based on FFT – Fast Fourier Transform, FWHT-Fast Walsh-Hadamard Transform and FDFI – Fast Impulse Frequency Determination. The errors determination is applied for the mass measurement of yarn using a capacitive sensor and for the measurement of yarn diame...
