紋縮圖器 的英文怎麼說
中文拼音 [wénsuōtúqì]
紋縮圖器
英文
pantograph-
Secondly, hyperspectral images are hard to compress because of their abundant details, complicated texture and insignificant special correlation. making use of the significant spectral correlation within the hyperspectral images, we propose an optimal linear predictor which makes the square error minimal
針對高光譜遙感圖像細節豐富紋理復雜，空間相關性弱，難于壓縮的特點，本文充分利用了高光譜遙感圖像的譜間相關性，設計出對相鄰譜段進行預測並將預測殘差均方降為最小的一種最佳線性預測器。People often think about the filter ' s characters of orthogonal, symmetry, regularity, but seldom synthetically think about some factors such as image texture or compression rate. in this paper used the same adaptive arithmetic coder for many filters, analyzed the effect factors synthetically for the best wavelet compression, and give some methods for selecting filter
本文對多種常見濾波器，採用相同的自適應量化編碼方法進行實驗，研究並分析了選擇濾波器時應該考慮的圖像紋理、濾波器長度、壓縮比等一些綜合因素，有效解決了在小波圖像壓縮過程中，如何更好的選擇濾波器的問題。Second, in this paper, we also research the arithmetic of wavelet and fractal, at last give a method to synthesize the two technologies. through experiments testify this method is feasible. choice of filter in wavelet image compression is a critical factor which affects image compression quality
選擇濾波器時，人們一般考慮正交性、對稱性、正則性、支撐集和消失矩階數等濾波器本身的性質，卻很少將他們與圖像紋理特徵、濾波器長度、壓縮比等因素綜合起來考慮。
