Digital Image Processing for Image Enhancement ... There is a strong influence of contrast ratio on resolving power and detection capability of images. Techniques for improving image contrast are among the most widely used enhancement processes. ... Vegetation has intermediate intensity values, as do most of the rocks. In the hue image, the low ...

The steps are (1) image processing, (2) pixels selection, (3) polynomial fitting, and (4) estimation of the contact angle. Image processing. In image processing, the coordinates of the contact point and the interfaces between brine–oil and brine–rock are identified using the open-source library scikit-image for the filters.

Rock mass structural data analysis using image processing techniques (Case study: Choghart iron ore mine northern slopes) ... algorithm in one of the images of rock masses in .

and costly. Fragmentation analysis by digital image processing is a low cost and quick method. Split system is one of the digital image processing software developed to compute the size distribution of fragmented rock from digital images. In this study, size distributions were analyzed by using Split Desktop ® system. In the analysis, the

A new approach to identify the texture based on image processing of thin sections of different basalt rock samples is proposed here. This methodology uses RGB or grayscale image of thin section of rock sample as an input and extracts 27 numerical parameters. A multilayer perceptron neural network takes as input these parameters and provides, as output, the estimated class of texture of rock ...

Since rock particle images vary from one to another, it is difficult or even impossible to design and develop one segmentation algorithm for all kinds of rock particle images. The presented segmentation algorithms were developed for just several types of rock particle images with certain characteristics with respect to segmentation [20].

In this paper we have proposed a new numerical approach based on image processing and multi-layer perceptron neural network that allowed us to classify carbonate rocks by grey level images digitized from thin sections, using the Dunham textural classification.

Abstract. In this paper, a procedure for calculating the size distribution of rock fragments using video images is described. The procedure utilizes a high-resolution video camera for image capturing in the field and a set of computer algorithms for processing the video images. The computer program first delineates the individual rock fragments ...

2.2. Image acquisition and processing. An image of a cylindrical rock sample with a diameter of 30 mm was acquired using a custom-built XCT scanner based on a CT-Alpha system (ProCon, Sarstedt, Germany) at the Institute for Geosciences laboratory in Mainz, Germany.The XCT scanner consisted of a Feinfocus microfocus X-ray tube (Yxlon, Hamburg, Germany) with a diamond …
