The experiments show that the proposed image compression and denoising method can significantly outperform those that are based on Bandelet or Contourlet transform in visual quality for the images with abundant edges and texture, and the peak signal to noise ratio is also increased by more than 0.1 dB.

实验结果表明，对于纹理和边缘丰富的图像，所提出的图像压缩和去噪方法在视觉质量上明显优于基于Bandelet或Contourlet变换的方法，峰值信噪比也提高了0.1dB以上。

Next, the Bandelet transform is taken on each directional subband. The proposed multidirectional and multiscale transform with critical sampling can represent the geometrical features such as edges and texture more sparsely, which is of great benefit to image compression.

原始的Contourlet变换有大于1的冗余度而不适于图像压缩的要求，采用传统的张量积小波变换取代其中的拉普拉斯金字塔式变换可获得非冗余的变换形式[8]，Bandelet变换是一种基于图像边缘的变换方法，它能自适应地跟踪图像的几何正则方向。

In this dissertation, the author first reduces the amount of computation and improves the transform speed by ameliorating the geometric angle-direction search methods. According to HVS properties that human eyes are not sensitive to the change of image's textures and edges, the dissertation proposes a digital watermarking algorithm based on HVS in improved Bandelet domain.

本文首先通过改进变换中的几何角度方向搜索方法降低了变换运算量，提高了变换速度，并依据HVS关于人眼对图像的纹理和边缘变换不敏感的特性，设计了一种基于HVS的改进Bandelet变换域图像数字水印算法。

The transform has the characteristics of multiscale geometric analysis of both Bandelet and Contourlet transforms, and it represents the edges and texture features more sparsely.

该变换兼有Bandelet变换和Contourlet变换的多尺度几何分析特性，能更稀疏地表示边缘和纹理特征。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
