Designing and implementing a system for Automatic recognition of Persian letters by Lip-reading using image processing methods
For many years, speech has been the most natural and efficient means of information exchange for human beings. With the advancement of technology and the prevalence of computer usage, the design and production of speech recognition systems have been considered by researchers. Among this, lip-reading techniques encountered with many challenges for speech recognition, that one of the challenges b...
متن کاملProcessing Digital Image for Measurement of Crack Dimensions in Concrete
The elements of the concrete structure are most frequently affected by cracking. Crack detection is essential to ensure safety and performance during its service life. Cracks do not have a regular shape, in order to achieve the exact dimensions of the crack; the general mathematical formulae are by no means applicable. The authors have proposed a new method which aims to measure the crack dimen...
متن کاملAutomatic Weed Mapping using Digital Image Processing
Digital image processing makes automatic weed detection possible. The system presented employs a mobile camera system which simultaneously photographs two geocoded images in two different spectral bands and compares them to each other. Pre-processing reduces the images to the outer contours of the plants. For their knowledge-based classification programmed with multi-invariant parameters, sampl...
متن کاملAutomatic Measurement of Eye Features Using Image Processing
This paper presents a camera based eye anthropometric measurement system that automatically computes the pupil size, the inter-pupillary distance, palpebral fissure (PF) and the marginal reflex distance (MRD). These values are in general manually obtained in ophthalmologic exams using a millimetric ruler or gauges, and therefore are subject to errors. Besides improving the accuracy and reliabil...
متن کاملAutomatic Correction of Lens Distortion by Using Digital Image Processing
Many inexpensive camera lenses, especially zoom lenses, suffer from very clear distortion. We show that even with such a lens near perfect images can be obtained by using a correction algorithm based on a simple mathematical model and without any special measuring tools. See Figures 9–12 for reallife examples. The most typical cases of distortion, barrel and pincushion distortion, are illustrat...
