چکیده
The aim of this paper is to show how image points can be extracted accurately. We will restrict our search to speciic points identiied by corners, which are stable given a sequence. Our approach makes use of a model{based corner detector. It matches a part of the image containing a corner against a predeened corner model. Once the tting is accomplished, the position of the corner in the image can be deduced by the knowledge of the corner position in the image. The validity of our approach has been proven with 4 independent tests. It is shown that the accuracy which can be achieved is 1/10th of a pixel.

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...

Unlike the frame type images, back-projection of ground points onto the 2D image space is not a straightforward process for the linear pushbroom imagery. In this type of images, best scanline search problem complicates image processing using Collinearity equation from computational point of view in order to achieve reliable exterior orientation parameters. In recent years, new best scanline sea...
متن کاملImprovement of the Classification of Hyperspectral images by Applying a Novel Method for Estimating Reference Reflectance Spectra
Hyperspectral image containing high spectral information has a large number of narrow spectral bands over a continuous spectral range. This allows the identification and recognition of materials and objects based on the comparison of the spectral reflectance of each of them in different wavelengths. Hence, hyperspectral image in the generation of land cover maps can be very efficient. In the hy...
متن کاملStochastic Fuzzy Discrimination Information Measure Cost Function in Image Processing
A new cost function based on stochastic fuzzy discrimination information measure is introduced in this paper. Focusing on their significant parts, this cost function is used to find the optimal value of threshold for denoising image. It is, in fact, an extension of fuzzy entropy cost function by the present author. Multivariable normal distribution is used for creating focus on significant part...
