Automatic Encoding

For the requirement of the department for aviation accident investigation, a computer information system of processing the broken tape of flight data recorder has been designed. The main principles of the system are that magnetic track images are first preprocessed using image processing techniques, furthermore, the position coordinates of tracks are obtained using image recognizing techniques, finally, the data corresponding to track coordinates are obtained by encoding the track coordinates using the serial-parallel scanning method that is specially designed. The accurate ratio of automatic encoding is 99.3%. The times of automatic encoding are reduced to proximate 5 seconds from about 4 hours of two operators for one frame track image. This system is significant for aviation accident investigations.

In this study, remote sensing and geographic information system (GIS) techniques were used in order to accomplish land cover change of Bozcaada Island, Turkey, by using multitemporal Landsat Thematic Mapper data. Digital image processing techniques were conducted for the processes of image enhancement, manipulation, registration and classification for land cover change analysis. The land cover changes between two different dates were visualized and analyzed by using Geographic Information System techniques. The results showed that remotely sensed data and GIS are effective and powerful tools for carrying out changes on land cover of the island and monitoring of its impact on the environment.

Green Areas

Article measures the distribution of green areas within the subdivisions of the municipality of Goiânia. It aims to verify if the regulation presented in Federal Law 6.766/1979, which regulates the Parcelamento do solo urbano it is being fulfilled with regard to the reservation of at least 10% of the total subdivision for the green and leisure areas. This is mainly an observation for a future scenario, there is an expectation of reducing the metric to 7.5%, to be provided for in the draft law of the New Master Plan. To obtain the data, techniques of Digital Image Processing and analyzing with Geographic Information System were applied. The results were surprising, because of the 1.089 subdivisions analyzed, 512 allotments, equivalent to 47.02% of the area, have coverage of green and leisure areas, less than 10%, thus, not complying with the current regulations provided for in the legislation. For new the 7.5% metric, this number reduces to 458, which may compromise the losses of 2.1 km² of these spaces.

Rotaviruses are spherical, double-shelled particles. They have been identified as a major cause of infantile gastroenteritis worldwide. In our earlier studies we determined the three-dimensional structures of double-and single-shelled simian rotavirus embedded in vitreous ice using electron cryomicroscopy and image processing techniques to a resolution of 40Å. A distinctive feature of the rotavirus structure is the presence of 132 large channels spanning across both the shells at all 5- and 6-coordinated positions of a T=13ℓ icosahedral lattice. The outer shell has 60 spikes emanating from its relatively smooth surface. The inner shell, in contrast, exhibits a bristly surface made of 260 morphological units at all local and strict 3-fold axes (Fig.l).The outer shell of rotavirus is made up of two proteins, VP4 and VP7. VP7, a glycoprotein and a neutralization antigen, is the major component. VP4 has been implicated in several important functions such as cell penetration, hemagglutination, neutralization and virulence. From our earlier studies we had proposed that the spikes correspond to VP4 and the rest of the surface is composed of VP7. Our recent structural studies, using the same techniques, with monoclonal antibodies specific to VP4 have established that surface spikes are made up of VP4.

The Brain

A brain tumor is an uncontrolled growth of abnormal brain tissue that can interfere with normal brain function. Although various methods have been developed for brain tumor classification, tumor detection and multiclass classification remain challenging due to the complex characteristics of the brain tumor. Brain tumor detection and classification are one of the most challenging and time-consuming tasks in the processing of medical images. MRI (Magnetic Resonance Imaging) is a visual imaging technique, which provides a information about the soft tissues of the human body, which helps identify the brain tumor. Proper diagnosis can prevent a patient's health to some extent. This paper presents a review of various detection and classification methods for brain tumor classification using image processing techniques.
