软分割约束边缘保持插值的半自动2D转3D
二维转三维 图割 随机游走 软分割
2017/1/4
半自动2D转3D将用户标注的稀疏深度转换成稠密深度,是解决3D片源不足的主要手段之一.针对现有方法利用硬分割增强深度边缘引入误差的问题,提出像素点与超像素深度一致性约束的边缘保持插值方法.首先,建立像素点深度和超像素深度传播的能量模型,通过像素点与所属超像素间深度差异的约束项将二者关联起来;其次,利用矩阵表示形式将两个能量模型的最优化转换成一个稀疏线性方程组的求解问题.通过超像素提供的约束项,可避...
中间绑定测试能够更早地检测出3D堆叠集成电路绑定过程引入的缺陷,但导致测试时间和测试功耗剧增.考虑测试TSV、测试管脚和测试功耗等约束条件,采用整数线性规划方法在不同的堆叠布局下优化中间绑定测试时间.与仅考虑绑定后测试不同,考虑中间绑定测试时,菱形结构和倒金字塔结构比金字塔结构测试时间分别减少4.39%和40.72%,测试TSV增加11.84%和52.24%,测试管脚减少10.87%和7.25%....
