Digital Image Analysis of Yellowstone National Park

Introduction
Remote sensing refers to the tele-observational surveying and mapping of physical, urban and environmental features. Remote Sensing is also a composite of many other subjects such as aerial photography, radar surveying, thermal surveying, weather forecasting and photogrammetry. It has now become quite common practice to use remotely sensed data to take inventory, monitor and develop effective management practices of our natural resources.

Objective
It is the purpose of this paper to further enhance the understanding of remotely sensed data in such a way that we may assist the human brain in the extraction and interpretation of this data through digital image analysis data manipulation techniques, such as rectification, enhancement and classification. The application of conventional and non-conventional image enhancement /classification procedures will be applied to an area of The Old Faithful section of the North Fork forest fire within Yellowstone National Park as it existed on September 8, 1988. They will also be applied to Nile Delta region of Egypt.

Conventional technology in the context of this paper refers to imagery that is uni-dimensional, that is, it has only one spectral band available for analysis. The term non-conventional will refer to imagery that has multi bands available for manipulation and analysis.

Methods of enhancement utilized in the multi-band portion of this project include:
- colour and histogram image enhancement
- normalization and image algebra enhancement
- filtering image enhancement
- band transformations (eigen pictures) image enhancement
- coventional methods of enhancement

Methods of classification utilized in this project include:
- signature training ( sampling)
- supervised classification, PPD, Mindis, Maximumlikliehood
- unsupervised classification, histogram equalization, clustering

Methods of enhancement used in uni-scene portion of this project include:
- histogram equalization uni-band
- filtering image enhancement

Data Acqisition
Data acquisition refers to the data by means of information gathering about the scale selection of the remote sensing formats and the target identification of the surveyed and mapped resources.

In this analysis we have acquired Landsat Thematic Mapper data which consists of seven spectral bands and covers a 512x512 picture element area. The Landsat ground resolution or pixel size is 30x30 metres which translates to an area coverage of 235.93 square kilometres of ground coverage, which is a subset region of the Yellowstone National Park.

The Nile Delta region is located in nothern Egypt and the data acquired was originally acquired for delta topgraphy. The data is Landsat MSS with one available band and covers a 580x640 picture element area. The Landsat MSS ground resolution is 80x80 metres which translates to an area coverage 2211.

Can We Legislate Digital Image Manipulation? Essay examples - Presentation of the Issue Photo manipulation has become very common now days, especially in magazines. “EVERYTHING is photoshopped. Every image you see on a magazine cover is not real” (F,Jim, 2010) Where editors edit photos by enhancing certain aspects or erasing “flaws” in order to achieve what has always been sought by humans: “perfection”. Or in realistic words: to achieve the stereotypic image of beauty from society’s perspective. In order to achieve this, a particular software is used in order to manipulate images.Photoshop is the most common photo manipulation software used....   [tags: Digital Photo Manipulation]

Computer Forensics: Issues in Preserving Digital Evidence and Forensic Investigation - Technology is constantly changing, and as the capabilities change, so do the issues in Forensic information technology (FIT). FIT is defined as the scientific use or application of information technology (IT) that is used to generate and present digital evidence to be used in courts, legal or other formal proceedings (Volonio). While the use of technology helps get things done faster, it also can present many issues if the proper procedures and tools are not used and followed. An existing issue in FIT is computer forensics, in regards to preserving digital evidence and effectively conducting a computer forensics investigation....   [tags: digital media, digital evidence]

Feature Extraction Using Digital Image Correlation for Pulsed Eddy Current Thermographic Images - Feature Extraction Using Digital Image Correlation for Pulsed Eddy Current Thermographic Images Abstract Pulsed Eddy Current (PEC) thermography is a new method in the field of Non-Destructive Testing and Evaluation (NDT&E). The diffusion of heat in a specimen can be characterised by analysing a sequence of PEC thermography images, which correspond to defects. This study takes advantage from the capabilities of PEC thermography in gaining quantitative information for angular defect characterisation through the analysis of the surface thermal distribution....   [tags: Research Analysis ]

Essay on Storytelling Through Digital Media - ‘The Matrix’ - A Non Linear Narrative The main focus of the first assessment was that of non linear multi narrative storytelling through digital media. The importance of structure in digital storytelling is emphasised by Miller (2004, pp 114) “In a work of digital storytelling, the structure not only supports the narrative and gaming elements but also helps determine the nature of the interactivity”. It was from this, that I realised how important it would be to structure my narrative effectively so that the user could enjoy the experience as much as possible....   [tags: Digital Media]

Essay on New Wavelet Based Image Denoising Method - Image Processing is any form of signal processing for which the input is an image or video frame; the output of image processing is set of parameters related to the image. The goal of our research presents a new wavelet based image denoising method to be compared with curvelet denoising and contourlet denoising. The Multi resoulution Analysis (MRA) transformation is implemented using the three transforms, Wavelet Curvelet and Contourlet. The wavelet transformation algorithm is implemented to compresses the essential information in a signal into few, large coefficients with in time and frequency transformation....   [tags: SNR, image processing, contourlet]

84 square kilometres of ground coverage. In addition to the above mentioned sources of data, a supplimental map has been attached with the defined study area.

Data Processing
Refers to the process whereby one observes, classifies. and analysis specific targets or features found on the imagery and defines and explains the importance of those results.

Data Application/Utilization
The surveying and mapping of either environmental, physical, or human resources from aerial photographs or satellite imagery. The main purpose of data application is to make an inventory, monitor, and make proper resource management plans for the future.

Conclusion
A comparison of the conventional (single band) and unconventional (multi-band) enhancement and classification is necessary to complete this analysis of image enhancement and image classification in digital image analysis. It is quite obvious that the multi-band data set was more useful and flexible when it came to classification and enhancement. Many methods of enhancement were applied to the multi-band data and there were a lot of methods to chose from, depending on the type of features that were to be highlighted. That is not to say that the conventional methods of classification and enhancement are obsolete. It only means you must chose the best methods of enhancement to highlight a particular area in which you are interested.
