The formula shows that the deflect degree first increases , then decreases , and its maximum increases while the compress rate decreases 分析表明,斜交橋下的水流流向偏轉角度隨斜交角度的增大先增大后減小,其極大值隨壓縮比的減小而增大。
The experiments show that this algorithm surpasses those traditional coding method in compressing rate and it is competitive in speed and time with those traditional coding method 實驗表明,這種算法在壓縮率上優于傳統的算法,在編碼和解碼速度上接近于傳統的數據編碼方法。
H . 263 + is one of the mature standards to deal with high compress rate and strong channel error correction ability , which could be perfectly used in wireless video communication areas 面向甚低碼率的h . 263 +標準則是能較好地解決高壓縮效率和強信道冗錯能力的成熟標準之一,能較好地應用于無線視頻通信領域。
Experimental results show when image compressing rate is high , decoded image of wavelet transform based compressing method can preserve objects outline well and has no block effect which may appear in dct block coding technique 從運行結果可以看出,當圖像壓縮率較高時,使用基于小波分析圖像壓縮方案的解碼圖像能保持清晰的輪廓,無dct塊編碼壓的方塊效應。
We decompose an image through the wavelet transform functions made by us , the original image can be better restored , and the experiment of single image shows the compressing rate is 50 : 1 . the compressing efficiency is further improved 用所構造的小波變換把圖像分解后,能比較好地恢復出原始圖像,從單幀圖像的實驗說明壓縮比可達50 : 1 ,進一步提高了壓縮效率。
