DB - Eris - Coordination-Free Consistent Transactions Using In-Network Concurrency Control.pdf Distributed storage systems aim to provide strong consistency and isolation guarantees on an architecture that is partitioned across multiple shards for scalability and replicated for fault tolerance. Traditionally, achieving all of these goals has required an expensive combination of atomic commitment and replication protocols – introducing extensive coordination overhead.

DB - Fast and General Distributed Transactions using RDMA and HTM.pdf Recent transaction processing systems attempt to leverage advanced hardware features like RDMA and HTM to significantly boost performance, which, however, pose several limitations like requiring priori knowledge of read/write sets of transactions and providing no availability support. In this paper, we present DrTM+R, a fast in-memory transaction processing system that retains the performance benefit from advanced hardware

The common wisdom is that distributed transactions do not scale. But what if distributed transactions could be made scalable using the next generation of networks and a redesign of distributed databases? There would be no need for developers anymore to worry about co-partitioning schemes to achieve decent performance. Application development would become easier as data placement would no longer determine how scalable an application is. Hardware provisioning would be simplified as the system ...

ARIES - A Transaction Recovery Method Supporting Fine-Granularity Locking and Partial Rollbacks Using Write-Ahead Logging.pdf Algorithm for Recouery and Isolation Exploiting Semantics), which supports partial rollbacks of transactions, finegranularity (e.g., record) locking and recovery using write-ahead logging (WAL). We introduce the paradigm of repeating history to redo all missing updates before performing the rollbacks of the loser transactions during restart after a system failure.

分别用SIFT、SURF、ORB做特征匹配要求用绿色线条画出两张图对应的匹配点（出3张图） 再使用RANSAC滤除离群点（参数自行调优）后用绿色线条画出两张图对应的匹配点（出3张图） 然后根据对应点分别计算图B到图A的单应变换矩阵（要求以矩阵形式清晰打印出来并截图，精度保留3位有效数字，出3张图） 根据计算的单应矩阵把第二张图变换到第一张图的坐标系下，与原图通过线性加权的方式融合（权重自行调优），可调用现成库，出3张图。
