considering the importance of adequate roughness coefficient estimation in river engineering studies, evaluation of image processing technique in estimating manning’s roughness coefficient in the surface layer of riverbeds carried out in this study. the mentioned approach evaluation conducted by implementing of sieving analysis and digital image processing methods simultaneously for a 7.5km rea...

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...

1. Abstract In this project, we propose a user-friendly image editing system, Fantasy Illustrator, in order to help people create a new work arbitrary by manipulating images from any collections user desired. In contrast with sophisticated operators Adobe Photoshop provided, our system classifies image editing operators into two critical operations: geometric based operation and tone based oper...

Preface The purpose of this brief review is to provide the reader with the necessary background to follow material in the book dealing with matrices and vectors, probability, and linear systems. The review is divided into three main sections, each dealing one of the three preceding topics. The following material is highly focused to the needs of someone needing a refresher in one of these topic...
