Vigra (island)

Vigra is an island in Giske Municipality in Møre og Romsdal county, Norway. The 20-square-kilometre (7.7 sq mi) island is located north of the islands of Valderøya and Giske, west of the mainland of Haram Municipality, and southwest of the island of Lepsøya (in Haram). Vigra has a road connection to the mainland via the Vigra Fixed Link, a series of tunnels and bridges that connect all the islands of Giske Municipality to the city of Ålesund to the south. The island was formerly part of Vigra Municipality.

The island is fairly flat and barren, although most land has been converted to agricultural uses. The highest point is the 122-metre (400 ft) tall Molnesfjellet on the north end of the island. The largest population centre on the island is the village of Roald on the northern part of the island, on the southeastern edge of Molnesfjellet. Vigra Church is the only church on the island.

Vigra has excellent walking trails along the seashore and over the hills. There are a number of beaches on Vigra including Blimsanden, Rørvikvågen, Blindheimsvika, Roald, and Molnes. Fishing is a popular activity on the island. Ålesund Airport is located on the island of Vigra. On 8 September 2011, the 77-year-old landmark Vigra transmitter, a medium wave broadcasting transmitter, was taken down.

Vigra

Vigra is a former municipality in Møre og Romsdal county on the west coast of Norway. It is located in the present-day Giske Municipality. The former municipality was made up of the island of Vigra along with many smaller islets surrounding it. The municipality existed from 1890 until 1964 when it was merged into Giske Municipality. The administrative centre of the municipality was the village of Roald, and Vigra Church was the main church for the municipality.

History

On 1 January 1890, the western islands in Haram Municipality were separated from Haram and established as Roald Municipality. The initial population was 794. In 1911, the name of the municipality was changed to Vigra. On 1 January 1964, the whole municipality of Vigra was merged into the neighboring Giske Municipality. Prior to the merger, the population of the municipality was 1,569.

VIGRA is the abbreviation for "Vision with Generic Algorithms". It is a free open source computer vision library which focuses on customizable algorithms and data structures. VIGRA component can be easily adapted to specific needs of target application without compromising execution speed, by using template techniques similar to those in the C++ Standard Template Library.

Features

Images and Multi-dimensional Arrays, Image Processing, Filters, Segmentation, Image Analysis, 3-dimensional Image Processing and Analysis, Machine Learning, Mathematical Tools, and Inter-language support.

VIGRA runs on the three major operating systems (Microsoft Windows, Mac OS X, and Linux). Since version 1.7.1, VIGRA provides Python bindings based on numpy framework.

History

VIGRA was originally designed and implemented by scientists at Heidelberg Collaboratory for Image Processing (HCI) University of Heidelberg. In the meantime, many developers have contributed to the project.

Application

CellCognition and ilastik uses VIGRA computer vision library.
