Description

一种数据处理方法及其装置
本申请要求于2022年10月20日提交中国国家知识产权局、申请号为202211292146.9、发明名称为“一种数据处理方法及其装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及人工智能领域，尤其涉及一种数据处理方法及其装置。
背景技术
人工智能(Artificial Intelligence，AI)是利用数字计算机或者数字计算机控制的机器模拟、延伸和扩展人的智能，感知环境、获取知识并使用知识获得最佳结果的理论、方法、技术及应用系统。换句话说，人工智能是计算机科学的一个分支，它企图了解智能的实质，并生产出一种新的能以人类智能相似的方式作出反应的智能机器。人工智能也就是研究各种智能机器的设计原理与实现方法，使机器具有感知、推理与决策的功能。
语言驱动的精确实例分割，是一种特殊的语义分割技术，指根据自然语言指导，在一幅图片中精确地分割出语言所描述的实例目标，其特点在于：1)传统语义分割模型为为属于同个类别的所有目标都预测同样的标签，并不区分同个类别中不同的目标，而语言驱动的精确实例分割，需要从多个同类目标中精确地识别出语言描述所对应的一个实例目标；2)语义分割模型需要预先定义一组语义类别的标签，从而学习分割出这些类别的目标，而语言驱动的精确实例分割可以接收更加灵活的自然语言输入，且不限目标类别。
由于自然语言输入的灵活性，语言驱动的实例分割方法主要依靠将自然语言句子编码和图像的视觉编码进行融合，从而在视觉特征图上激活和语言编码相关性高的区域，然而这种跨模态特征融合的方案其挑战主要在于两个方面，首先是实例目标定位不准确，在多个拥挤的同类目标中，无法准确地锁定单个实例目标；其次是预测的掩膜不够准确，容易溢出到相邻的同类目标上，上述问题也同样存在于目标检测任务中。
发明内容

其中，图像可以包括目标对象在内的多个对象，每个第二嵌入向量对应于所述图像中的一个对象，多个第二嵌入向量中的一个或多个嵌入向量可以对应于目标对象。应理解，这里的“对应”可以理解为，第二嵌入向量用于描述所述图像中的一个对象的特征，通过神经网络得到的第二嵌入向量可以将图像中的不同对象进行区分，以便后续的预测过程中能够以对象为粒度。
相当于将图像特征从像素粒度变为以目标对象为粒度，也就是在跨模态特征融合中引入目标整体性约束，将属于同个目标的像素当做一个整体来和语言编码进行融合，以目标为单位来激活实例区域，可以有效解决现有语言驱动的精确实例分割方法目标定位和掩膜预测或者检测框预测不准确的问题，从而提升模型的处理精度。

应理解，本申请实施例中的和模型推理过程相关的步骤涉及AI相关的运算，在执行AI运算时，终端设备和服务器的指令执行架构不仅仅局限在上述介绍的处理器结合存储器的架构。下面结合图3对本申请实施例提供的系统架构进行详细的介绍。
图3为本申请实施例提供的系统架构示意图。如图3所示，系统架构500包括执行设备510、训练设备520、数据库530、客户设备540、数据存储系统550以及数据采集系统560。
执行设备510包括计算模块511、I/O接口512、预处理模块513和预处理模块514。计算模块511中可以包括目标模型/规则501，预处理模块513和预处理模块514是可选的。
其中，执行设备510可以为上述运行图像处理类应用程序的终端设备或者服务器。
数据采集设备560用于采集训练样本。训练样本可以为多个图像等。在采集到训练样本之后，数据采集设备560将这些训练样本存入数据库530。
训练设备520可以基于数据库530中维护训练样本，对待训练的神经网络(例如本申请实施例中的跨模态语言模型(例如包括文本编码器、图像编码器、目标编码器等))，以得到目标模型/规则501。
应理解，训练设备520可以基于数据库530中维护训练样本，对待训练的神经网络进行预训练过程，或者是在预训练的基础上进行模型的微调。
需要说明的是，在实际应用中，数据库530中维护的训练样本不一定都来自于数据采集设备560的采集，也有可能是从其他设备接收得到的。另外需要说明的是，训练设备520也不一定完全基于数据库530维护的训练样本进行目标模型/规则501的训练，也有可能从云端或其他地方获取训练样本进行模型训练，上述描述不应该作为对本申请实施例的限定。
根据训练设备520训练得到的目标模型/规则501可以应用于不同的系统或设备中，如应用于图3所示的执行设备510，该执行设备510可以是终端，如手机终端，平板电脑，笔记本电脑，增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备，车载终端等，还可以是服务器等。
具体的，训练设备520可以将训练后的模型传递至执行设备510。
在图3中，执行设备510配置输入/输出(input/output，I/O)接口512，用于与外部设备进行数据交互，用户可以通过客户设备540向I/O接口512输入数据(例如本申请实施例中的图像等)。
预处理模块513和预处理模块514用于根据I/O接口512接收到的输入数据进行预处理。应理解，可以没有预处理模块513和预处理模块514或者只有的一个预处理模块。当不存在预处理模块513和预处理模块514时，可以直接采用计算模块511对输入数据进行处理。

最后，I/O接口512将处理结果提供给客户设备540，从而提供给用户。
在图3所示情况下，用户可以手动给定输入数据，该“手动给定输入数据”可以通过I/O接口512提供的界面进行操作。另一种情况下，客户设备540可以自动地向I/O接口512发送输入数据，如果要求客户设备540自动发送输入数据需要获得用户的授权，则用户可以在客户设备540中设置相应权限。用户可以在客户设备540查看执行设备510输出的结果，具体的呈现形式可以是显示、声音、动作等具体方式。客户设备540也可以作为数据采集端，采集如图所示输入I/O接口512的输入数据及输出I/O接口512的输出结果作为新的样本数据，并存入数据库530。当然，也可以不经过客户设备540进行采集，而是由I/O接口512直接将如图所示输入I/O接口512的输入数据及输出I/O接口512的输出结果，作为新的样本数据存入数据库530。
值得注意的是，图3仅是本申请实施例提供的一种系统架构的示意图，图中所示设备、器件、模块等之间的位置关系不构成任何限制，例如，在图3中，数据存储系统550相对执行设备510是外部存储器，在其它情况下，也可以将数据存储系统550置于执行设备510中。应理解，上述执行设备510可以部署于客户设备540中。

其中，终端设备可以通过云端提供的API，将相关参数(例如图像)发送至服务器，服务器可以基 于接收到的参数，得到处理结果等)，并将处理结果返回至至终端。
关于终端以及服务器的描述可以上述实施例的描述，这里不再赘述。
如图4示出了使用一项云平台提供的语言驱动的图像处理类云服务的流程。
1.开通并购买内容审核服务。
2.用户可以下载内容审核服务对应的软件开发工具包(software development kit，SDK)，通常云平台提供多个开发版本的SDK，供用户根据开发环境的需求选择，例如JAVA版本的SDK、python版本的SDK、PHP版本的SDK、Android版本的SDK等。
3.用户根据需求下载对应版本的SDK到本地后，将SDK工程导入至本地开发环境，在本地开发环境中进行配置和调试，本地开发环境还可以进行其他功能的开发，使得形成一个集合了语言驱动的图像处理类能力的应用。
4.语言驱动的图像处理类应用在被使用的过程中，当需要进行语言驱动的图像处理时，可以触发语言驱动的图像处理的API调用。当应用触发语言驱动的图像处理功能时，发起API请求至云环境中的语言驱动的图像处理类服务的运行实例，其中，API请求中携带图像，由云环境中的运行实例对图像进行处理，获得处理结果。
5.云环境将处理结果返回至应用，由此完成一次的本申请实施例提供的方法调用。
由于本申请实施例涉及大量神经网络的应用，为了便于理解，下面先对本申请实施例涉及的相关术语及神经网络等相关概念进行介绍。
(1)神经网络
神经网络可以是由神经单元组成的，神经单元可以是指以xs(即输入数据)和截距1为输入的运算单元，该运算单元的输出可以为：
其中，s＝1、2、……n，n为大于1的自然数，Ws为xs的权重，b为神经单元的偏置。f为神经单元的激活函数(activation functions)，用于将非线性特性引入神经网络中，来将神经单元中的输入信号转换为输出信号。该激活函数的输出信号可以作为下一层卷积层的输入，激活函数可以是sigmoid函数。神经网络是将多个上述单一的神经单元联结在一起形成的网络，即一个神经单元的输出可以是另一个神经单元的输入。每个神经单元的输入可以与前一层的局部接受域相连，来提取局部接受域的特征，局部接受域可以是由若干个神经单元组成的区域。
(2)transformer层
参照图5，图5为一种transformer层的架构示意，如图5所示，神经网络包括嵌入层和至少一个transformer层，至少一个transformer层可以为N个transformer层(N大于0的整数)，其中，每个transformer层包括依次相邻的注意力层、加和与归一化(add&norm)层、前馈(feed forward)层和加和与归一化层。在嵌入层，对当前输入进行嵌入处理，得到多个嵌入向量；在所述注意力层，从所述第一transformer层的上一层获取P个输入向量，以P个输入向量中的任意的第一输入向量为中心，基于预设的注意力窗口范围内的各个输入向量与该第一输入向量之间的关联度，得到该第一输入向量对应的中间向量，如此确定出P个输入向量对应的P个中间向量；在所述池化层，将所述P个中间向量合并为Q个输出向量，其中transformer层中最后一个transformer层得到的多个输出向量用作所述当前输入的特征表示。
(3)注意力机制(attention mechanism)
注意力机制模仿了生物观察行为的内部过程，即一种将内部经验和外部感觉对齐从而增加部分区域的观察精细度的机制，能够利用有限的注意力资源从大量信息中快速筛选出高价值信息。注意力机制可以快速提取稀疏数据的重要特征，因而被广泛用于自然语言处理任务，特别是机器翻译。而自注意力机制(self-attention mechanism)是注意力机制的改进，其减少了对外部信息的依赖，更擅长捕捉数据或特征的内部相关性。注意力机制的本质思想可以改写为如下公式：
其中，Lx＝||Source||代表Source的长度，公式含义即将Source中的构成元素想象成是由一系列的数据 对构成，此时给定目标Target中的某个元素Query，通过计算Query和各个Key的相似性或者相关性，得到每个Key对应Value的权重系数，然后对Value进行加权求和，即得到了最终的Attention数值。所以本质上Attention机制是对Source中元素的Value值进行加权求和，而Query和Key用来计算对应Value的权重系数。从概念上理解，把Attention可以理解为从大量信息中有选择地筛选出少量重要信息并聚焦到这些重要信息上，忽略大多不重要的信息。聚焦的过程体现在权重系数的计算上，权重越大越聚焦于其对应的Value值上，即权重代表了信息的重要性，而Value是其对应的信息。自注意力机制可以理解为内部Attention(intra attention)，Attention机制发生在Target的元素Query和Source中的所有元素之间，自注意力机制指的是在Source内部元素之间或者Target内部元素之间发生的Attention机制，也可以理解为Target＝Source这种特殊情况下的注意力计算机制，其具体计算过程是一样的，只是计算对象发生了变化而已。
(4)自然语言处理(natural language processing，NLP)
自然语言(natural language)即人类语言，自然语言处理(NLP)就是对人类语言的处理。自然语言处理是以一种智能与高效的方式，对文本数据进行系统化分析、理解与信息提取的过程。通过使用NLP及其组件，可以管理非常大块的文本数据，或者执行大量的自动化任务，并且解决各式各样的问题，如自动摘要(automatic summarization)，机器翻译(machine translation，MT)，命名实体识别(named entity recognition，NER)，关系提取(relation extraction，RE)，信息抽取(information extraction，IE)，情感分析，语音识别(speech recognition)，问答系统(question answering)以及主题分割等等。
(5)预训练语言模型(pre-trained language model)
预训练语言模型是一个自然语言序列编码器，为自然语言序列中的每个词进行编码成为一个向量表示，从而进行预测任务。它的训练包含两个阶段。在预训练(pre-training)阶段，该模型在大规模无监督文本上进行语言模型任务的训练，从而学习到一个词表示。在微调(finetuning)阶段，该模型利用预训练阶段学到的参数做初始化，在文本分类(text classification)，序列标注(sequence labeling)等下游任务(downstream task)上进行较少步骤的训练，就可以成功把预训练得到的语义信息成功迁移到下游任务上来。
(6)反向传播算法
卷积神经网络可以采用误差反向传播(back propagation，BP)算法在训练过程中修正初始的超分辨率模型中参数的大小，使得超分辨率模型的重建误差损失越来越小。具体地，前向传递输入信号直至输出会产生误差损失，通过反向传播误差损失信息来更新初始的超分辨率模型中参数，从而使误差损失收敛。反向传播算法是以误差损失为主导的反向传播运动，旨在得到最优的超分辨率模型的参数，例如权重矩阵。
(7)损失函数
在训练深度神经网络的过程中，因为希望深度神经网络的输出尽可能的接近真正想要预测的值，所以可以通过比较当前网络的预测值和真正想要的目标值，再根据两者之间的差异情况来更新每一层神经网络的权重向量(当然，在第一次更新之前通常会有初始化的过程，即为深度神经网络中的各层预先配置参数)，比如，如果网络的预测值高了，就调整权重向量让它预测低一些，不断地调整，直到深度神经网络能够预测出真正想要的目标值或与真正想要的目标值非常接近的值。因此，就需要预先定义“如何比较预测值和目标值之间的差异”，这便是损失函数(loss function)或目标函数(objective function)，它们是用于衡量预测值和目标值的差异的重要方程。其中，以损失函数举例，损失函数的输出值(loss)越高表示差异越大，那么深度神经网络的训练就变成了尽可能缩小这个loss的过程。
语言驱动的精确实例分割，是一种特殊的语义分割技术，指根据自然语言指导，在一幅图片中精确地分割出语言所描述的实例目标，其特点在于：1)传统语义分割模型为为属于同个类别的所有目标都预测同样的标签，并不区分同个类别中不同的目标，而语言驱动的精确实例分割，需要从多个同类目标中精确地识别出语言描述所对应的一个实例目标；2)语义分割模型需要预先定义一组语义类别的标签，从而学习分割出这些类别的目标，而语言驱动的精确实例分割可以接收更加灵活的自然语言输入，且不限目标类别。
由于自然语言输入的灵活性，语言驱动的实例分割方法主要依靠将自然语言句子编码和图像的视觉 编码进行融合，从而在视觉特征图上激活和语言编码相关性高的区域，然而这种跨模态特征融合的方案其挑战主要在于两个方面，首先是实例目标定位不准确，在多个拥挤的同类目标中，无法准确地锁定单个实例目标；其次是预测的掩膜不够准确，容易溢出到相邻的同类目标上。
为了解决上述问题，本申请实施例提供了一种数据处理方法。下面结合附图对本申请实施例的数据处理方法进行详细的介绍。
参照图6，图6为本申请实施例提供的一种数据处理方法的流程示意，如图6所示，本申请实施例提供的一种数据处理方法，可以包括步骤601至603，下面分别对这些步骤进行详细的描述。
601、获取图像对应的第一图像特征以及文本对应的文本特征；所述文本的语义对应于目标对象，且所述文本指示从所述图像中预测目标对象对应的区域。
在一种可能的实现中，文本的语义可以指示从图像中确定目标对象对应的掩码区域(图像分割任务)或者是检测框(目标检测任务)。
在一种可能的实现中，所述文本的语义用于描述所述目标对象的特征。例如，图像中包括两个花瓶，分别是红色和黄色，文本可以为红色的花瓶，例如，图像中包括两个花瓶，分别处于图像的左侧和右侧，文本可以为左侧的花瓶。
在一种可能的实现中，在获取到图像以及文本之后，可以对图像和文本进行特征提取以及对齐，得到图像对应的第一图像特征以及文本对应的文本特征。
在一种可能的实现中，所述获取图像对应的第一图像特征以及文本对应的文本特征，具体包括：通过图像编码器处理所述图像，得到所述图像对应的图像特征，通过文本编码器处理所述文本，得到所述文本对应的第一文本特征，并通过双向注意力机制融合所述第三图像特征以及所述第一文本特征，得到所述图像对应的第一图像特征以及所述文本对应的文本特征。
示例性的，图像编码器fv(或者可以称之为视觉编码器)可以对于给定的视觉图像I，采用Swin Transformer作为视觉编码器去提取多层级的视觉特征，将Swin Transformer中多个阶段(以四个阶段为例)产生的多尺度视觉特征，并记为
示例性的，文本编码器fl(或者可以称之为语言编码器)可以使用多层BERT(以12层为例)作为语言编码器，对于给定的语言表达W＝{wi}i＝1,…,T，其中T是表达式的长度。首先使用基于WordPiece的BERT分词器获得嵌入词向量E，将E送入BERT的隐藏编码层中去提取语言特征，为了能和Swin Transformer中四个阶段输出的视觉特征进行对齐，可以将BERT中每三层聚合，定义为一个阶段，这样就可以获得和视觉特征数量相同的语言特征，记为参照图7，同时可以在后面也会利用[CLS]标记对应的语言特征，使其作为一个全局的语义表达向量，记为Lg。
在一种可能的实现中，可以使用文本-像素对齐Word-pixel alignment模块来实现双向注意力机制，Word-pixel alignment模块是一种跨模态带门限的双向注意力模块，在图像和句子的编码阶段，促使视觉和语言特征在特征空间去对齐。可学习的特征门限机制，是为了防止更新融合后的特征时淹没原始特征信息。Word-pixel alignment的对齐效果可以如图8所示，通过Word-Pixel Alignment模块，在视觉和语言信息编码阶段，将语言信息融入到视觉编码中，同时将视觉信息融入到语言编码中，从而使得句子的单词特征和图片中对应的像素特征在跨模态特征空间建立相关性。
在一种可能的实现中，跨模态双向注意力模块BiAttn将视觉和语言特征在特征空间进行信息交互。使用该模块来融合双编码器每一阶段的视觉语言特征。可选的，其操作定义如下：
V′i,L′i＝BiAttn(Vi,Li),i∈{1,…,4}；
BiAttn函数的具体计算过程如下：


其中dk是视觉语言联合嵌入空间的维度，Wv,Wl,W′v,W′l均为投影矩阵。可选的，为了防止融合特征V′i,L′i会完全覆盖掉原有的特征Vi和Li的信息，设计了一个多层感知器MLP当做GATE来控制融合特征流入的信息量大小：
V′i←Gate(V′i),L′i←Gate(Li′)；
F′i＝GATE(Fi)＝MLP(Fi)⊙Fi；
其中Fi表示来在BCA模块的融合特征，F′i表示被抑制过后的融合特征，⊙表示矩阵逐元素乘法。MLP是一个两层感知机，第一层是线性层，随后是ReLU激活函数，第二层是线性层，随后是双曲正切激活函数。
在一种可能的实现中，为了更好的捕捉高层语义和生成像素级别的融合特征，可以使用一个多头注意层来融合来自视觉语言编码器的高层特征。首先，将高层的视觉特征Vo和语言特征Lo都投影到相同的特征空间，然后将它们拼接成一个融合特征Fo，其之后被送入交叉注意层。在拼接之前，将一个可学习的位置向量ep加在投影后的视觉特征上。最后交叉注意层输出特征So。上述运算可以被表述为如下公式：

So＝CrossAttn(Fo)+Vo,Fo＝[V′o；L′o],；
其中为投影矩阵，[；]为张量拼接操作。
在一种可能的实现中，为了将像素级别的特征上采样到原图大小获得最终的分割图，可以构建一个分割头。示例性的，分割头的输入可以为So和多尺度视觉特征然后获得如下输出：
其中ρ是一个两层的卷积网络，每一层都是一个3×3的卷积加上ReLU和批归一化，Up表示双线性插值上采样，γ表示1*1的卷积，将的每个像素进行特征投影，分割头的输出记为Y1。
602、根据预设的多个第一嵌入向量以及所述第一图像特征，通过神经网络，得到多个第二嵌入向量，每个第二嵌入向量对应于所述图像中的一个对象；每个所述第二嵌入向量和所述第一图像特征用于融合得到一个对应的第二图像特征。
其中，神经网络可以根据第一图像特征，将多个第一嵌入向量处理成多个第二嵌入向量，其中，每个第二嵌入向量可以对应于目标对象的一个候选区域，不同的第二嵌入向量可以对应于目标对象的不同或存在重叠的候选区域。
相当于将图像特征从像素粒度变为以目标对象为粒度，也就是在跨模态特征融合中引入目标整体性约束，将属于同个目标的像素当做一个整体来和语言编码进行融合，以目标为单位来激活实例区域，可以有效解决现有语言驱动的精确实例分割方法目标定位和掩膜预测或者检测框预测不准确的问题，从而提升分割精度。
在一种可能的实现中，所述神经网格包括多个transformer层。
示例性的，以图像分割为例，Sentence-object alignment模块，首先基于word-pixel align好的特征，生成可能的目标masks，再将自然语言句子特征和目标masks进行对齐align，从而更加精确地定位目标实例，如图9所示。本申请实施例设计了一个掩膜生成器MaskGenerator，基于编码器的输出So预测N个可能的目标掩膜。掩膜生成器由一个6层的Transformer解码器组成。其输入为So和N可学习的第一嵌入向量(也就是查询向量Q)，输出为N个第二嵌入向量(也就是目标掩膜特征向量编码Qo)，即：
Qo＝MaskGenerator(Q,So).；
603、根据所述文本特征和所述多个第二嵌入向量之间的相似度，确定每个所述第二嵌入向量对应的权重，多个所述权重用于和所述多个第二图像特征进行融合，以确定所述目标对象对应的预测区域。
由于多个第二嵌入向量中仅有部分是对应于目标对象的，在得到多个第二嵌入向量之后，可以根据文本特征为每个第二嵌入向量分配一个权值，权值较高的第二嵌入向量最有可能包含文本所指的目标对象。
示例性的，以图像分割任务为例，可以根据文本特征Lg为Qo的每个掩码向量(第二嵌入向量)分配一个权值Qw，Qw中较高的权重表明相应的掩码最有可能包含语言所指的对象。随后通过将Qo和Y1相乘得到N个掩码预测YN。最后，将YN和Qw相乘得到最后的掩码预测M，这个过程可以表示如下：
Qw＝softmax(sim(Lg,Qo)),
其中，sim(,)表示余弦相似度函数，表示广播张量乘法。
图7为本申请实施例的一个网络架构示意，其中，其整体架构设计遵寻了经典的编码器—解码器的范式，编码器部分由一个视觉编码器和一个语言编码器来提取视觉和语言特征，Word-Pixel Alignment(WPA)模块在视觉和语言编码的中间层，实现跨模态交互。然后使用一个交叉注意层将视觉和语言编码器的输出做跨模态融合。解码器部分由一个生成N个掩码查询向量的掩码生成器，一个将像素特征上采样的分割头和一个Sentence-Object Alignment模块(SOA)，其根据语句特征对输出的掩码查询向量赋权，同时加该利用该权重，对分割头生成的分割特征进行加权求和获得最终的分割掩码。
针对于上述模型的训练过程，以图像分割任务为例，对于参考图像分割而言，图像中的每一个像素都要被归类到前景或者背景，因此该任务可以被视为一个像素级别的二分类任务。具体来说，使用双线性插值将M上采样到原图大小，得到M′。令M′和(真实掩码)每一点i的值分别为m′i和分割损失形式如下：
其中σ表示sigmoid函数，j表示训练批次中的第j个图像。
此外，为了增强模型分离前景和背景的能力，可以使用一个像素级的对比损失函数来作为分割损失的辅助函数。该函数减小目标物体内的像素特征的距离，增大目标物体内像素特征和物体外像素特征的距离，如图10所示。
将真实掩码放缩到和分割特征图Y1一样的大小。令Y1中每一点i的向量为yi。然后利用的先验将yi划分出正负样本。对于每一点i而言，如果等于0，那么yi属于负样本集合N，记为否则yi属于正样本集合P，记为之后将正样本和负样本的均值向量分别记为和辅助损失函数形式如下：


其中τ是温度系数，最后，总损失函数如下：
模型训练结束后，在推理阶段，输入一幅图片，以及一个自然语言句子描述图片中的一个实例目标，模型会直接预测出该实例目标的掩膜M或者检测框，将其上采样插值回原图大小，并进行二值化，即可分割出实例目标。
接下来结合试验介绍本申请的有益效果：
参考图像分割常用的数据集有三个分别为：RefCOCO，RefCOCO+和RefCOCOg(也被称为G-Ref)。这三个数据集的图像都是来自于MSCOCO数据集，并各自配上了不同的语言标注。RefCOCO和RefCOCO+的语言标注是通过一个名为ReferitGame的游戏生成的，RefCOCO由142,209个自然语言标注和19,994张图片构成，RefCOCO+由141,564个自然语言标注和19,992张图片构成。RefCOCO和RefCOCO+两个数据集的主要区别在于RefCOCO+不允许在语言标注中使用类似“left”，“front”之类的定位词。因此，相较于RefCOCO而言，RefCOCO+数据集更加具有挑战性。G-Ref数据集上的语言标注是来源于Amazon Mechanical Truk，它包含有85,474个语言标注和26,711张图片。同时该数据集有两种划分方式，分别是UMD划分和Google划分。相较于RefCOCO和RefCOCO+而言，G-Ref的语言标注更加复杂多变，其句子的平均长度也是要大于RefCOCO和RefCOCO+数据集上句子的平均长度，这就使得G-Ref成为一个更加有挑战性的数据集。
原始输入数据为RGB图像，0-1掩码矩阵，语言标注字符串。其中图像部分数据的预处理为：对于训练数据将RGB图像归一化，正则化之后，通过双线性插值放缩到统一的分辨率448*448。同时0-1掩码矩阵经过最邻近插值放缩到和RGB图像一致的分辨率。对于测试数据只需要对RGB图像进行上述处理，不需要对0-1掩码矩阵进行最邻近插值。语言部分数据的预处理为：使用HuggingFace库中的BertTokenizer，将输入字符串标记化。BertTokenizer是基于WordPiece嵌入方法，其字典的大小为30,000。对于每一个标记化后的序列，第一个标记都是一个特殊的[CLS]标记。如果输入的是多个句子，那么在句子与句子之间会插入另一个特殊的[SEP]标记。
采用参考图像分割常用的三种度量方法来评估模型的性能，分别是全局交并比(oIoU)，平均交并比(mIoU)和prec@X。这三种度量方法都是目标识别的常用度量指标交并比(IoU)，其主要用来表示预测区域和真实区域的相似程度。在参考图像分割中，交并比的求法可以简化如下：给定预测掩码M和真实掩码其交并比定义如下：
全局交并比是所有测试图像的交集之和比上并集之和，平均交并比是所有测试图像交并比的平均值，prec@X是交并比大于某一阈值X的图像占所有测试图像的百分比，实验中X的取值通常为0.5，0.6，0.7，0.8，0.9。
表1与现有技术方法在RefCOCO和G-Ref两个数据集上的比较

在表1中，将CoupAlign与之前SOTA方法在RefCOCO和G-Ref上比较oIoU。RefCOCO数据集提供的语言标注，包含了许多位置词语，例如：“The closest girl on the right”。这要求模型不仅需要理解名词与物体之间的对应关系，还需要理解方位词表示的物体间的位置关系。与最新的SOTA方法LAVT比较，CoupAlign在RefCOCO的val，testA和testB上分别提升了1.97％，1.94％，1.79％。G-Ref上的语言标注相较于RefCOCO有更为复杂的语法结构，同时平均句子长度也更长。例如：“chocolate dessert directly in front of us in the center”这类句子需要更加细粒度的单词—像素对齐，更加准确的句子—掩码对齐，更加全面地理解语言。如表1所示在G-Ref上，CoupAlign在val和test上超过LAVT大约1.6％和0.13％。两个数据集的各个子数据集上的结果均超过现有的SOTA，证明了方法的有效性。
单词像素对齐使得跨模态的交互同时发生在编码的底层和高层阶段。在表2中，可以发现，在移除单词像素对齐模块之后，模型在oIoU这一指标上面下降了大约4.3％，这一点表明编码阶段的单词像素对齐模块的存在十分必要。同时当将双向注意力机制替换为单向注意力机制时，模型在oIoU这一指标上面下降了2％左右。这表明不仅是从语言到视觉的注意，从视觉到语言的注意力也十分的重要。当句子目标对齐模块移除之后，模型的oIoU指标下降了大约1.7％。这一点表明句子目标对齐模块对掩码的约束的效果，有助于提高CoupAlign预测的准确性。在表2的最后两行展示了移除辅助损失函数之后的对比效果，在移除辅助损失函数之后，模型在oIOU指标上下降了大约1％，这证明了辅助损失函数增强模型前景和背景分离能力有助于CoupAlign更好得进行多层次的对齐。
表2消融实验
为了验证的单词像素对齐模块和句子目标对齐模块可以提供准确并且持久的对齐。在图11A中可视化了对齐模块中间层的注意力图，如图11A所示，可以看见单词像素对齐模块高亮了与单词语义最相关的像素区域。值得注意的是，参考图像分割的语言标注的词汇库比传统的语义分割的词汇库要大很多。在这种情况下，CoupAlign不仅能够捕捉区分不同词性的词汇，同时对同义名词也有比较好的分辨能力。例如：其可以分辨“child”，“man”，“lady”等同义名词，但是这些在语义分割的数据集中常常都模糊地被定义为“person”类别。关于句子目标对齐模块，按照与句子语义相似度从大到小的顺序可视化了掩码预测。相似度越大的掩码与目标物体重合度越大，相似度越小的掩码与目标物体重合越小。在图11A中，可以看到句子目标对齐模块，使得模型可以关注到不同物体，从而感知到物体间的位置关系。并且因为引入了目标整体性约束，使得模型的分割预测较少得产生镂空，破碎等现象。
在图11B中，可视化模型最终预测结果的一些例子。CoupAlign在同类目标拥挤的场景下具有很强的定位能力。
