一种基于苗种活力图像特征的水产育苗质量分级方法及系统

本发明公开了一种基于苗种活力图像特征的水产育苗质量分级方法及系统，涉及图像处理技术领域。该基于苗种活力图像特征的水产育苗质量分级方法，通过获取连续帧苗种图像序列并划分局部处理区域，提取图像变化信息构建观测变化状态向量，基于该向量确定前景处理区域并构建动态环境参照集，建立局部环境扰动传播矩阵进行环境扰动变化与非环境变化分离，获得候选非环境变化分量，经关联构建候选运动证据链并判定有效运动轨迹事件，计算置信权重以构建苗种活力特征向量，本发明通过对苗种活力特征向量与候选运动证据链进行质量评估处理，确定育苗质量等级，从而降低了将环境波动误判为苗种活动的概率，使育苗质量分级结果更贴近苗种的实际活动水平。

一种基于水体指标时序学习的对虾育苗风险预警方法及系统

本发明公开了一种基于水体指标时序学习的对虾育苗风险预警方法及系统，涉及水产育苗数据处理技术领域。该方法获取水体指标序列和最近一次苗种状态检测数据，根据苗种状态检测数据生成育苗风险基准值并确定评估时刻；按固定监测周期识别水体指标状态片段，依据阶段承接关系连接形成跨周期水体指标演化过程，标定过程位置并生成水体过程记录；调用预训练的累计风险变化量预测模型生成起止累计风险变化量，经差值计算及汇集得到区间风险变化量，结合育苗风险基准值生成预测风险值，确定风险等级和异常水体指标并输出预警结果。本发明减少水体异常过程被周期割裂及多个独立异常过程共用整体育苗风险值造成的预警偏差。
