| 3. | Quantifying the performance of image denoising schemes by using the mean square error , the performance of the robust local threshold scheme is demonstrated and is compared with the universal threshold scheme
用均方差衡量去噪性能，实验表明用鲁棒局部阈值去噪法好于全局阈值去噪法。 |
| 4. | This thesis proposes a scheme of data encryption based on the ( m , n ) - threshold scheme and elliptic curve cryptosystem in which users are handled as an individual - user and a group - user
本文提出了一种基于( m ， n ) -门限方案和椭圆曲线密码体制的数据加密方案。在该方案中，用户分为单人用户和群组用户两种类型。 |
| 5. | The threshold scheme is actually a particular case of the vector space secret sharing scheme . therefore the vector space secret sharing scheme can find more applications than the threshold scheme . in the above two schemes , every participant is required verifying the shares of the other participants , and the computation complexity is relatively high
在上述两个方案中，每一个参与者都需对其余参与者出示的子秘密进行验证，验证工作量很大，有时在实际当中需要采用计算量比较小的方案，并且能够发现欺诈者的存在。 |
| 6. | We import a lowpass filter to smooth the loss ratio , adjust sending rate according to the smoothed result . we present an adaptive low threshold scheme regulating the low threshold according to the history record of sending rate adjustment to utilize efficiently the network bandwidth , and reduce the oscillation of sending rate . we find that such a rate adjustment can shorten congestion period and reduce packet loss
为使发送端在网络负载处于低载状态时，能迅速地提高码率，充分利用网络带宽，同时对网络当前的负载状况又不过于敏感，避免出现“振荡调节服务质量”的情况，本文提出了一种自适应下门限调节方案，根据历史记录动态调节下门限值，使整个传输过程既能充分利用带宽又不引起网络拥塞，从而减小时延，降低丢包率，同时减小了发送速率的振荡性。 |
| 7. | The functions of this scheme are as follows : the encryption of plaintext based on the ( m , n ) - threshold scheme by a group - user and the decryption of ciphertext by an individual - user ; the encryption of plaintext by an individual - user and the decryption of ciphertext based on the ( m , n ) - threshold scheme by an group - user ; the encryption of plaintext and the decryption of ciphertext by individual - users ; the encryption of plaintext and the decryption of ciphertext based on the ( m , n ) - threshold scheme by group - users
在加密和解密的过程中，群组用户都需要进行密钥(私钥)的恢复和认证。方案实现了以下几个方面的功能：基于( m ， n ) -门限方案的多人加密，单人解密。单人加密，基于( m ， n ) -门限方案的多人解密。 |
