| 1. | Field coding typically works better when there is fast picture - to - picture motion
场编码一般用在快速运动图象中。 |
| 2. | The code that is generated by this refactoring operation is modeled by the encapsulate field code snippets
此重构操作生成的代码将由“封装字段代码段”来建模。 |
| 3. | The picture - level adaptive frame field coding paff selects frame coding or field coding once for one picture
图像级的帧场自适应算法对每一帧选择一次帧编码或者场编码模式。 |
| 4. | Compression and access efficiency are two key problems for light field coding , while few works consider them both
压缩效率和随机接入性能是光场压缩的两个核心问题，目前鲜见综合考虑以上因素的技术。 |
| 5. | Adaptive frame field coding techniques have been adopted in many international video standards for interlaced sequence coding
为了提高隔行序列的压缩效率，帧场自适应编码技术在很多国际视频标准中都得到了应用。 |
| 6. | Frame coding or field coding can be adaptively selected on a picture - by - picture basis and also on a more localized basis within a coded frame
帧编码还是场编码可以自动选择，原则上基于图象与图象之间的变化，以及编码图象内部的局部化特征。 |
| 7. | When the frame field adaptation is applied on the picture level , the coding efficiency is improved greatly , compared with the pure frame coding or the pure field coding
与没有帧场自适应的帧编码或者场编码相比，当在图像级使用帧场自适应技术时，编码效率得到很大提高。 |
| 8. | Taking the radial forging process of the rd2 axle for example , the characteristics of the forging heating and forging craft and radial process in sliding method have been analysed with establishing the sliding field code and doing a speed diagram of the radial forging deformed process
摘要以rd2车轴径向锻造为例，分析了其锻造加热及锻造工艺的特点，并且用滑移法分析径向锻造变形过程，建立了外摩擦影响下的滑移场模式，并做出了与之相对应的速端图。 |
| 9. | When picture adaptive frame / field ( paff ) is utilized to interlaced sequences , two fields can be combined into one frame , which is encoded in frame coding ; besides , they can also be encoded in field coding separately . adopting field or frame coding can be determined by coding performance adaptively
图像级帧场自适应( paff )技术在处理隔行序列时,可将两场合成一帧,按照帧编码方式进行,也可以将其作为两场分别编码;采用帧或场编码可根据编码效果自适应选择。 |
| 10. | According to the aforementioned characteristics , the core algorithms proposed in this paper is that selection of frame / field is determined before encoding , where field coding is chosen when motion is acute , whereas , frame coding is chosen when motion is mild , and the coding scenario of the previous frame is applied for other circumstance
基于上述特点,本文核心算法为:编码前进行决策,运动剧烈时选用场编码,运动平缓时选用帧编码,其他情况延续上一帧编码方式。 ssd曲线一致性说明ssd的变化可以描述运动剧烈程度,但因其分布松散,难以直接使用。 |
