Abstract
Dye-specks such as streaks, barre, or bands pose serious quality problems in final textile products. Image processing and analysis techniques have been applied to the objective evaluation of the fabric in terms of fabric detects. Histogram analysis of the fabric yarn scale image effers fundamental information of the overall image, while the luminance profile plot of firs specific information of the streaky area within the image. Streak length, area, and the distribution meascrements through image processing techniques such as histogram equalization, thresholding, binarization were carried out. 24imensional fiequency analysis such as FFT(int courier transformation) gives detailed view of the streak pattern and the fabric structure itself These analyses results might provide numerical bases for the possible criteria of the fabric quality evaluation.
