視覺噪聲 的英文怎麼說
中文拼音 [shìjiàozàoshēng]
視覺噪聲
英文
visual noise-
In the process of processing image, image ' s vision effect is improved by some image enhance technique such as neighboring region average and pixel expanding. in accord with the feathers of the soil microphotograph, a three - level segmentation scheme is used to segment the soil microphotograph
在圖像處理過程中，對圖像進行了增強處理改善圖像視覺效果，採用了諸如灰度變換、改進的鄰域平均法和像素點擴張法改善圖像對比度以及消除圖像中的噪聲。Raise the threshold if you are using a usb cam or are in a visually noisy environment
如果使用usb攝像機或者處于高視覺噪聲環境中，那麼可以提高這個閾值。Human ocular apperceive is truly a robust character recognition system which can adapt to all kinds of noise
人類視覺感知毫無疑問是一個魯棒性很強的、能抵禦實際中可能遇到的各種變形和各種干擾噪聲的文字識別系統。The mutual excitation between the local stimuli satisfying the rules of curve distribution ( position and orientation continuity ) called curve self - excitation is a useful method to discover and enhance curves and to inhibit noise. the present approaches used parallel connection structure division which did not acquire satifactory effect. this paper presents the idea of random time division and dynamic self - excitation, for different curves performing random time - division searches, time coincidence filtering, and self excitation accumulation. the principle is given
利用空間分佈滿足曲線規則（位置和定向連續性）的局部刺激之間的相互激勵，稱為曲線自激，這是發現視覺邊界曲線和抑制局部噪聲的有效手段.過去的工作均採用并行結構區分的計算方式，曲線自激並沒有達到滿意的效果.本文提出隨機時分動態自激的計算方案，對不同的曲線實施隨機時分的搜索、時間一致性濾波、和自激積累等機制.本文給出了實現的原理方案In general, a watermark system must satisfy the two basic requirements : imperceptibility and robustness. in this thesis, we proposed a frequency - based watermarking algorithm using toral automorphisms, in which a kind of toral automorphism is employed to mix a recognizable binary image ( bw ), which contains the copyright information, into a noise - like signal
演算法簡單描述如下：首先用一個環形自同構映射把要嵌入的數字水印映射成偽隨機噪聲，然後把該偽隨機噪聲嵌入到宿主數據頻域的低頻段中，接著把得到的頻域系數進行相應的逆變換得到嵌入水印的圖象，最後對該嵌入水印的圖象進行視覺掩蔽處理。On the base of the analysis, we build up the vector fields of neighborhood variation ; put our emphasis on the description of the image edges and the domains of visual similar grey - level with the vector fields. after that, we find out the two methods used to detect the edges, the one with the biggest vector field, and the other with the perpendicular vector - pair of the biggest variation difference. the neighborhood size has got the great influence
在此基礎上，提出了基於鄰域灰度變化矢量場的圖像分割思想;建立了圖像鄰域灰度變化矢量場，並重點分析了鄰域灰度變化矢量場與圖像視覺邊緣、區域等特徵之間的關系;建立了最大鄰域灰度變化矢量的邊緣檢測運算元模型，基於鄰域灰度變化矢量場最大正交差異對的邊緣檢測運算元及區域檢測運算元模型;分析了鄰域選擇對邊緣擴展、噪聲抑制的影響。Noises will degrade the visual quality of captured video and affect efficiency of other video - processing device, e. g. the noises will degrade the quality of video compression
這會嚴重地影響採集視頻的視覺質量，並降低了其他后繼處理模塊的性能，比如噪聲信號會降低視頻壓縮演算法的質量。Experiment result shows that this algorithm avoids over - enhancement of noise while enhancing image details with good visual effect
實驗結果表明，該演算法可以有效地增強圖像的細節信息，減小噪聲的增強幅度，改善圖像的視覺效果。分享友人
