- Example Sentences:
| 1. | The author begins with this facet of the algorithm which can reduce the number of the matching of bloks in the process of the search , and therefore designs an optimized fractal image compression algorithm which aims to decrease the complexity of the fractal encoding and reduce encoding time
摘要从减少搜索匹配块的数目入手，提出了一种旨在降低分形编码的复杂度，缩短编码时间的分武力像压缩的改进算法。 | | 2. | Theoretically , fractal dimension has powerful ability to classify image blocks , which results in big speed - up ratio in fractal encoding ; and fractal dimension is a continuous value , which enables us to adjust the quality of decoded images by changing the number of classes
在理论上，由于这种维数具有很好的分类能力，使得这种方法可取得很大的加速比；由于这种维数是连续量，还可通过改变分类数目来调节解码图像的质量。 | | 3. | Note that in fractal encoding , each range block is to compare with domain blocks after some grey - level affine map . hence we first put forward a kind of image quadrature invariant of affine maps above , which can be thought of a generalization of mario feature
由于在分形编码时值域块实际上是与经过灰度仿射变换之后的定义域块进行比较，因此我们首先提出了一种在灰度仿射变换下保持不变的图像矩不变量，它可看作是mario特征的推广。 | | 4. | On the basis of the authors ’ results published in this journal [ 67 ] , this paper further proposed two strategies which improved both quality and speed of fractal encoding : one , a priori adding additive white gaussian noise into the image being encoded to reduce the domain blocks that are unlikely to meet the constraint on contrast scaling factors ; the other , range blocks with small standard deviations are directly approximated by the constant block ( i . e . , all the
在笔者原有结果[计算机仿真, no . 8 , 2004 ]的基础上,本文提出进一步提高解码图像质量和编码速度的方案:一是预先在待编码图像中添加高斯白噪声以进一步减少不满足对比度因子约束的domain块的数目;二是对小方差range块直接用其均值块代替以进一步加快编码速度。 | | 5. | Theoretically , this quadrature can classify image blocks effectively , which bring out big speed - up ratio in fractal encoding ; and this feature is a continuous value , which enables us to adjust the quality of decoded images by changing the number of classes . our experimental results show that , comparing with exhaustive search , when the class number is 25 , we obtain 20 times speed - up ratio , with only image degeneration of 2 . 08db , at the same compression ratio
_ }速比;这种不变量也是连续量，大量的数值实验表明，因此还可通过改变分类数目来调竹解码图像的质量在压缩比相同的前提下，与全局搜索法相比，块分为25类时，可取得约20倍的加速比，而解码质量只相差2 |
