Today, in the age of artificial intelligence and machine learning, Data mining and Image processing are two important platforms. GA and GP are value based and program based randomized searching tools respectively and these two are very much useful in the fields' data mining and image processing for handling different issues. In this chapter, a review is made on ability of GA and GP in some applications of these two fields. Here, the selected subfields of data mining are market analysis, fraud detection, risk management, sports analysis, protein interaction, classification of data, drug discovery and feature construction. The similar in image processing are enhancement and segmentation of images, face recognition, photo mosaic generation, data embedding, image pattern classification, object detection and Graphics Processor Unit (GPU) development. The efficiencies of GA and GP in these particular applications are analyzed with corresponding parameters, comparing with other non-GA and non-GP approaches of the corresponding subfields.

Abstract. This paper presents a new tool for large-area photo-mosaicking (LAPM tool). This tool was developed specifically for the purpose of underwater mosaicking, and it is aimed at providing end-user scientists with an easy and robust way to construct large photo-mosaics from any set of images. It is notably capable of constructing mosaics with an unlimited number of images on any modern computer (minimum 1.30 GHz, 2 GB RAM). The mosaicking process can rely on both feature matching and navigation data. This is complemented by an intuitive graphical user interface, which gives the user the ability to select feature matches between any pair of overlapping images. Finally, mosaic files are given geographic attributes that permit direct import into ArcGIS. So far, the LAPM tool has been successfully used to construct geo-referenced photo-mosaics with photo and video material from several scientific cruises. The largest photo-mosaic contained more than 5000 images for a total area of about 105 000 m2. This is the first article to present and to provide a finished and functional program to construct large geo-referenced photo-mosaics of the seafloor using feature detection and matching techniques. It also presents concrete examples of photo-mosaics produced with the LAPM tool.

The City

Benghazi has been photographed many times from the air, but few are aware that the layout of the city was-recorded in air photographs taken very early in the twentieth century. (International Archiv für Photogrametrie 1914). These photographs provide an unusually detailed impression of the streets, public buildings and dwellings of the city, and also allow students of the Middle Eastern and North African city to observe the evolution of the city by studying later comparative photography. Libya is especially rich in such imagery at least for the recent past (Allan 1969). The purpose of this brief study is to draw attention to the rich source of evidence available in air photo records through an interpretation of an early twentieth century image along with just one of the more recent photographs taken in this area in 1965.The determination of the date of the old photo-mosaic is the first task of interpretation. The journal in which it was published appeared in 1914, which places the image earlier than the outbreak of World War I and possibly prior to the occupation of northern Libya by Italian forces in 1911. The photo shows no evidence of the buildings which were constructed by the Italian colonists. Nor has there been any significant transformation at the harbour. In the eastern extremity of the early twentieth century city there is an assemblage of military equipment, accommodation and transport. Whether this is evidence of Turkish or Italian occupation is difficult to determine, and so we must be satisfied at this stage to date the photographs between 1911 and 1913.

The objective of this study was to investigate the influence of the development of road quality (surfacing condition and road type) and road quantity (road density and distance to main road) on forest extent changes in a region in Zagros forests of Iran over the three time periods of 1960s, 2000s and 2010s. Ranks of 1 to 5 were assigned to road quality. Forest extent changes were analysed on digital aerial photo mosaic. The Spearman and Pearson correlation coefficients were used to test the relationship between the road parameters and forest extent changes. Results showed that rural-forest road network has more influence on settlement development. Forest extent was correlated negatively with the road quality. Moreover, there were more disturbances to native forests closer to roads. It was concluded that forest cover decrease was associated with physical parameters including access to roads, cultivation practices, road quality and settlement development.

Since 1988, the professional staff of Architectural Preservation Studio (APS) has been involved with the conservation of Frank Lloyd Wright’s Fallingwater in Mill Run, PA. Designed and erected from 1935 to 1939 as a weekend home for the Kauffman family, the complex consists of the main house and guest house.<br><br> After five years of reports and prototype repairs, we produced a two-volume master plan. Using original Frank Lloyd Wright drawings from Avery Library as background drawings, we measured every surface and reproduced the drawings in CAD, also developing elevations of every room. Stone-by-stone drawings of every flagstone floor and terrace scheduled to be lifted were also created using overlapping film photography that was assembled into a photo mosaic. By 2005, we designed, administered and completed a four-phase exterior restoration, with the paint-stripping and repainting of interior rooms being performed during the brief winter period when the building is closed to the public on an ongoing basis.<br><br> In 2016, we were invited back to the site to review conditions and advise on routine maintenance. At that time we proposed to re-document the buildings, this time using laser-scanning. Laser-scanning of the exterior was performed in May of 2016, and of the interior in March 2017, each over the course of four days. This paper will make a comparison between manual and digital techniques in terms of Fallingwater’s documentation.
