冗餘度壓縮 的英文怎麼說
中文拼音 [rǒngyúdùyāsuō]
冗餘度壓縮
英文
redundancy reduction-
Although the image ' s modulus maximums have been greatly compressed, but they still contain the redundant data, which is the information used in lower - scale modulus images has been used in higher - scale modulus images
但是經過小波模極大值變換后得到的模圖像信息雖然得到了壓縮，但仍存在冗餘，即低解析度上使用過的信息在高解析度下重復使用。Compared with average filter method, the method can eliminate the noise information in the measurement points more effectively. a data compression method was proposed to compress the measurement points that include huge redundancy under certain accuracy. then segmentation and smoothing method for the measurement points to identify the jump edge, crease edge and smooth edge and optimize the measurement points were conducted so as to reconstruct the surface and generate the manufacturing path conveniently
在一定的精度條件下，該方法可對包含大量冗餘的測量數據進行壓縮處理；對測量數據進行分片處理，拾取測量數據中的階躍邊界點、褶皺邊界點和光滑邊界點並優化測點數據，從而便於對測量數據進行nurbs （ non - uniformrationalb - spline ）重建和加工路徑生成等后續處理。( 2 ) the relation of each image feature point and the most evident curve membership is discovered, such relation can be used to reduce redundancy of parameter space, depresses computational effort and suppresses the false accumulator cells etc. the most evident curve membership is then fed to the original image space, the information of image pixels can be recovered, the shorter line can be found, the bad line can also be repaired and the pr ecision of beeline detection can be improved
（ 2 ）提出圖像特徵點與參數點一一對應的可能性，實現了圖像特徵點對應于參數空間某一最優參數點，減少了參數空間的冗餘量，降低了計算量，壓縮了偽累積點；並將最優參數點反饋回圖像平面，恢復圖像特徵點信息，可以檢測出較短線段，修補破損直線，提高了直線檢測的精度。Fractal image compression, as a fire - new scheme of image compression, based on the self - similarity and proportion of image, it implements the image data compression by eliminating the image geometry redundancy
基於分形的圖像壓縮編碼方法是一種全新的編碼方法，它利用的是圖像的自相似性及比例特性，通過消除圖像的幾何冗餘度來實現圖像數據的壓縮。What the part of the principle of video reduced narrates mainly is that there is plentiful temporal redundancy between adjacent frames in a video sequence for their " similarity " and there is a lot of spatial redundancy in each pixel within a frame for their " similarity ", the video is compressed by reducing spatial and temporal and statistical redundancy with the technology of dpcm and dct and huffman encoding
視頻壓縮原理部分介紹了視頻序列的相鄰幀之間的「相似」而存在大量的時間冗餘度，幀內各相鄰象素的「相似」而存在大量的空間冗餘度。通過使用dpcm 、 dct和huffman編碼去除了時間、空間及統計冗餘度，從而實現了視頻的壓縮。In the process of image compression, considering that the three or more layers bp networks have some redundancies in the weights between input layer and meddle layer so as to effect the network ' s study speed and compression quality, we bring forward a new two layers back propagation networks and it ' s arithmetic
考慮到利用三層及三層以上bp網路對圖像壓縮，其有效信息是中間層單元上的輸出值和中間層與輸出層之間的連接權，而輸入層與中間層的連接權是冗餘的，以至於對學習速度和壓縮質量有負面影響。分享友人
