灰度畸變 的英文怎麼說
中文拼音 [huīdùjībiàn]
灰度畸變
英文
tonal distortion-
12 orrite c, blecua s, herrero j e. shape matching of partially occluded curves invariant under projective transformation. computer vision and image understanding, 2004, 93 : 34 - 64
此外，匹配的特徵相似性度量結合了非均勻有理b樣條的畸變估計和局部的圖形窗口交叉相關性，從而融合了幾何結構和圖像灰度的相似性。But influenced by a great deal of factors in laser and only strong stability scanning as one again, for instance, the un - stability of laser instrument, inconsistency of decaying to the laser of every part, etc. in the scanner, can lead to the fact intensity of laser on piece fluctuate, cause, scan systematic formation of image quality drop finally
另外，又針對激光掃描系統中的由於掃描非線性等固有因素的存在，所導致掃描成像灰度畸變的現象，提出了一種利用數字補償校正技術對固有因素進行激光光束光強的逐點補償的新方法。本設計不僅適用於激光掃描系統，對于其它各個應用領域，都有參考價值。To this problem a series of image rectification procedure which utilize geometric rectification theory in vehicle license recognition system are pointed out : we first locate vehicle license and execute the edge detection and binary conversion, then proceed calibration in which we use two calibration scheme looking for control point coordinate, one based on the hough transformation, the other based on image analysis method, and finally realize image correction in geometrical transform and bilinear gray interpolation method
針對此問題本文給出了一套將幾何畸變校正技術應用到汽車牌照自動識別系統中的車牌圖像校正方法：首先提取牌照信息，並對圖像進行邊緣檢測和二值化的預處理；然後提出了基於hough變換控制點提取和基於圖像分析法的控制點提取的兩種實時標定方法；最後通過空間坐標變換和灰度插值完成圖像的校正。According to this, we propose a new way to renew the traditional method of subjective image quality evaluation, different to only use mse ( mean square error ) and psnr ( peak signal - to - noise ratio ) to evaluate merely on radiation distortion, and complemented quantitative description on compressed image distortion o it is significant to choose the format of video transferation and measuring precision calculation of tracking and measuring systems based on images
中國科學院長春光機與物理研究所博士學位論文據此提出了不同於傳統的僅用均方誤差（ mse ）和峰值信噪比（ psnr ）來評價圖像灰度輻射畸變的新思路，補充了對壓縮圖像幾何畸變的定量描述。這對于基於圖像的測量跟蹤系統中數字圖像傳輸方式的選擇，以及評價壓縮解壓演算法對測量精度的影響有重要意義。分享友人
