Color Texture Analysis of Moving Vocal Cords Using Approaches from Statistics and Signal Theory
نویسندگان
چکیده
Textural features are applied for detection of morphological pathologies of vocal cords. Cooccurrence matrices as statistical features are presented as well as filter bank analysis by Gabor filters. Both methods are extended to handle color images. Their robustness against camera movement and vibration of vocal cords is evaluated. Classification results due to three in vivo sequences are in between 94.4% and 98.9%. The classification errors decrease if color features are used instead of grayscale features for both statistical and Fourier features.

Automatic Classification of Leukoplakia on Vocal Folds Using Color Texture Features
In this paper we present novel approaches for the computer aided diagnosis of leukoplakia on the vocal folds based on video endoscopic images of the larynx. The approaches applied for the classification of the vocal fold surface tissue are texture analysis methods, which have been enhanced to use spatial information as well as color information in one combined color texture approach. The multis...
متن کاملRole of the Internal Superior Laryngeal Nerve in the Motor Responses of Vocal Cords and the Related Voice Acoustic Changes
Background: Repeated efforts by researchers to impose voice changes by laryngeal surface electrical stimulation (SES) have come to no avail. This present pre-experimental study employed a novel method for SES application so as to evoke the motor potential of the internal superior laryngeal nerve (ISLN) and create voice changes.Methods: Thirty-two normal individuals (22 females and 10 males) par...
متن کاملDynamic Texture Analysis and Synthesis Using Tensor Decomposition
Dynamic textures are sequences of images showing temporal regularity, such as smoke, flames, flowing water, or moving grass. Despite being a multidimensional signal, existing models reshape the dynamic texture into a 2D signal for analysis. In this article, we propose to directly decompose the multidimensional (tensor) signal, free from reshaping operations. We show that decomposition technique...
متن کاملTexture Analysis using Rough Texton
The present paper derived a new texture classification tactic using textons and rough sets. Texton is a statistical approach used to analyze the texture of an image. Textures will be developed only if the side elements lie within the contiguity. Texton Image has the discrimination power of color, texture and shape features. In the proposed tactic texton using rough texture spectrum and color fe...
متن کاملThe Influence of Bernoulli’s Effect on the Function of the Vocal Cords
This research is a follow-up to the previous research which was dealing with the creation of the simulation of the vocal cords function using FEM. This paper focuses on how the vocal cords function is affected by Bernoulli’s effect, while using model [1] is used. It is well known, that Bernoulli’s effect is connected with the suction in the air space between the vocal cords. This is caused by t...
