毕业论文之图像处理的译文

Abstract: The image intensification is refers to in the enhancement image the useful information, it may be a distorted process, its goal is must strengthen the visual the sharp image will become clear or emphasized certain is interested the characteristic, suppresses is not interested the characteristic, causes it improvement picture quality, the rich information content, the enhancement imagery interpretation and the recognition effect imagery processing method. First chapter introduced the wavelet algorithm history and in the reality application first. Then analyzes several kind of wavelet transformations the method, including continual wavelet transformation, separate wavelet transformation and two-dimensional separate wavelet transformation. In this topic experiment, is precisely two-dimensional separate wavelet transformation which uses. Second chapter simply introduced the image intensification two kind of methods: Spatial domain ydo law and frequency range law. Will carry on about the image intensification further discussion in the third chapter under the MATLAB environment. Third chapter first makes the simple introduction to the MATLAB development and introduces it emphatically in various domains strong point. Then the key research image gradation level revises, and gives each algorithm the MATLAB procedure and the movement result. In deepening theory knowledge foundation further familiar MATLAB use. Finally enclosed experimental three sections of procedures: The two-dimensional separate wavelet transformation, and improves the visual quality based on the DWT image auto-adapted enhancement and outputs. Key words: Image intensification; MATLAB; Wavelet transformation; Separate wavelet transformation

Abstract: The computer application technology popularizes day by day, the film and television program manufactures by the original professional operates transforms also may carry on the correlation manufacture into the present non-professional. Traditional simulated video image processing is usually called the video frequency image editing or the linear edition, along with the digital phantom technology and multimedia computer technology integration, the digital video frequency phantom processing technology has had the qualitative leap, in traditional video frequency image editing foundation, also has had a brand-new edition technology - - computer non-linearity edition technology, compares with the traditional linear edition, the non-linear edition system except may avoid the machine, the magnetic tape which because edits repeatedly creates loses, outside the picture drop in quality, may realize the function which the traditional linearity edition can not hold a candle, this technology has played the significant role in modern film and television manufacture each link. Premiere is one uses in the video frequency, the audio frequency edition function formidable non-linearity edition software, therefore, my graduation project "2008 Olympic Games Promotional films" complete with Premiere. But, Premiere has the insufficiency in very many aspects, has affected the movie effect instance, captions edition, audio frequency and picture special effect. In view of these situations, in the design process, I adopted the small grizzly bears Kara OK captions manufacture software to make up the captions the disappointment, and so on carried on using Photoshop and Xara3D processes the substantial picture content, after but conformity source material. These means and the measure, had achieved the good effect, causes the movie to be maturer and to be perfect. The article introduced in detail my manufacture process, the technical measure and the final manufacture effect which adopts in view of the existence question.
