图像面积 meaning in Chinese

image area
picture area

Compared with the traditional algorithm ( computation error is more than 10 percents ) , the computation precision of the proposed algorithm was greatly increased
利用本算法，图像面积和周长的计算误差最大不超过2 。
The computation precision of metal image area and girth was increased , and the algorithm for traditional method of computing image was improved
研究提高金属图像面积和周长的计算精度，对计算图像像素的经典链码方法加以改进。
4 . to the problem of time exhaustion in using the gvf snake model , a " open - window " method is put forward which is more pertinence and time saving than the traditional method by restricting the calculating area in a small window . a comparison result is given to prove the high efficiency of the proposed method
试验对比分析了不同开窗区域的时间消耗情况，当开窗区域面积为图像面积的1 4时， gvfsnake迭代计算20次和40次能节省时间约一半，迭代60次则计算时间为原来的34左右。
