Processing 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 کاملDigital Image Processing Image Processing and Restoration
The purpose of this paper is to explore techniques for image enhancement and recovery, especially as they relate to reversing or minimizing the effects of noise degradation. The specific goal of the paper is to attempt to recover readable characters from a license plate image. I start with a short background on the importance of enhancement and then cover some of the technical approaches and te...

With the large cost involved in launching satellites, probes, sensors to keep an eye on the resources and entities of commercial value necessitates to strengthen the processing of procured data at ground stations. The emphasis is laid on enhancing the quality for easy human interpretation and reducing the quantity for easy storage and transmission. The first sine qua non involves the capturing ...

2. A sampled (but not quantized) image, whose brightness before quantization, in each spatial position, can take values in the range [0mV;250mV], has the linear histogram of its brightness represented (approximately) in Fig. 2.a). After the quantization, the histogram of the resulting digital image is the one in Fig. 2.b). Then, most likely, the quantizer that was used is: a) an 8 bit uniform q...

(a) Aerial images: • LANDSAT images from one year compared to ones from the next year. Slightly different area covered, different orientation angle, illumination, crops, etc. • Guidance systems: compare an image of the ground with a stored reference image (b) Medical images: • CT chest scans taken 6 months apart: has the tumor gone away or gotten worse? Some difficulties: Different lung sizes b...
