H. 26l / h. 264 is a new video compression standard provided by itu - t and iso / iec, which faces to very low rate video communication. it uses a new dct transform method as 4 * 4 integer dct. it can reduce block effect, while it is clear and easy to realizen, has high precision, computes fast and costs less memory
H . 26l / h . 264是itu - t與iso / iec聯合提出的一種較新的面向甚低碼率視頻通信應用的視頻圖像壓縮標準，採用了一些新的編碼技術，使用了新的dct變換方法: 4 4整型dct變換，該變換具有減小方塊效應，演算法明晰簡單、易於實現，運算結果精度高且不會溢出，運算速度快，佔用內存小等優點。 -
In one of the tests we showed participants a block of faces with wide - spaced eyes and then asked them to compare these with a face that had narrow - spaced eyes
其中的一個實驗是，先向實驗者展示一系列眼距比較寬的面孔，然後讓他們與另一張眼距比較窄的面孔進行對比。 -
For the frontal upright faces in gray images, a knowledge - based face detection method is proposed. a knowledge base is established according to prior knowledge of faces. the integral image method is used to calculate sub - block ' s statistic values and the computation burden is reduced significantly
針對灰度圖像，提出一種基於知識的人臉檢測方法，根據人臉檢測先驗知識，在傳統的馬賽克方法基礎上，建立了人臉檢測知識庫，採用積分圖方法計運算元塊的統計量，從而顯著地提高了檢測速度。
