具体实施方式
图1是根据本公开的实施例示出的一种视频服务平台的架构示意图。如图1所示，该系统包括网络10、服务器11、若干电子设备，比如手机12、手机13和手机14等。
服务器11为包含一独立主机的物理服务器，或者该服务器11为主机集群承载的虚拟服务器。在运行过程中，服务器11运行某一应用的服务器侧的程序，以实现该应用的相关业务功能，比如在该服务器11运行视频服务平台的程序的情况下，实现为该视频服务平台的服务端。而在本公开的一个或多个实施例的技术方案中，由服务器11通过与手机12-14上运行的客户端相互配合，实现包含弹幕的视频画面的展示方案。
在本公开的实施例中，视频服务平台不仅能够实现视频服务功能，还能够作为诸多其他功能的集成化功能平台，比如对于区域绘制操作的检测、备选轮廓模板的展示与选取、备选对象模板的展示与选取、目标区域的确定、目标画面的渲染等，本公开的一个或多个实施例并不对此进行限制。
手机12-14只是用户使用的一种类型的电子设备。实际上，用户还能够使用诸如下述类型的电子设备：平板设备、笔记本电脑、掌上电脑(PDAs，Personal Digital Assistants)、可穿戴设备(如智能眼镜、智能手表等)等，本公开的一个或多个实施例并不对此进行限制。在运行过程中，该电子设备运行某一应用的客户端侧的程序，以实现该应用的相关业务功能，比如当该电子设备运行视频服务平台的程序时，实现为该视频服务平台的客户端，例如手机12实现为视频提供客户端，手机13和手机14实现为视频播放客户端。
需要指出的是：视频服务平台的客户端的应用程序被安装在电子设备上，在该电子设备上启动并运行该客户端；当然，在采用诸如HTML5技术的在线客户端的情况下，无需在电子设备上安装相应的应用程序，即可获得并运行该客户端。
而对于手机12-14与服务器11之间进行交互的网络10，包括多种类型的有线或无线网络。
当前的视频播放平台能够为观众提供弹幕展示功能，即在视频播放过程中同时展示与视频相关的弹幕。目标视频的原始画面包括画面图层和弹幕图层，即所展示的目标视频的原始画面是基于画面图层和位于画面图层上方的弹幕图层渲染得到的。
如图2所示，客户端所播放目标视频对应的视频画面201中展示有弹幕202。用户观看到的视频画面201相当于位于上方的弹幕图层203和位于下方的画面图层204的叠加展示。因为弹幕图层203位于画面图层204上方，所以在根据弹幕图层203和画面图层204渲染而成的视频画面201中，弹幕展示在视频画面上方，导致弹幕对视频画面的遮挡。
为避免弹幕对视频画面的遮挡，相关技术中由服务端提前确定视频中目标对象的对象位置，然后将视频和该对象位置提供至客户端，客户端在渲染该位置处的视频画面时将弹幕渲染在对象下方，从而在该对象位置处仅展示目标对象而不展示相应弹幕，实现对该目标对象的防挡展示效果。然而，因为上述方式中的目标对象和相应的防挡位置由服务端提取前确定，而与用户行为无关，因此最终实现的防挡展示效果难以符合观众用户的观看需求。
图3是根据本公开的实施例示出的一种视频画面的展示方法的流程图。如图3所示，该方法应用于客户端，包括以下步骤：
步骤302，响应于用户针对目标视频的原始画面实施的区域指定操作，确定原始画面中的目标区域，该目标区域中的视频画面被根据画面图层和位于画面图层上方的弹幕图层渲染得到。
其中，目标区域中的视频画面为目标视频在目标区域中的原始画面。也即是客户端响应于对目标视频的原始画面的区域指定操作，确定原始画面中的目标区域。其中，该原始画面包括目标视频的画面图层和位于画面图层上方的弹幕图层，该画面图层和弹幕图层为 目标视频对应的完整的图层，区域指定操作是指确定原始画面中的目标区域的操作。
在本公开的实施例中，用户设置完成的目标区域，即为最终展示时仅展示画面不展示弹幕的区域，亦即在目标区域中实现弹幕的防挡展示功能的区域。为便于描述本方案，下文中将目标区域也称为“防挡区域”，特此说明。
客户端通过多种方式确定目标区域。在一些实施例中，用户在观看展示的原始画面过程中，在原始画面中实施绘制目标区域的操作，相应的，客户端检测用户在原始画面中绘制的目标区域，即客户端响应于在原始画面中的区域绘制操作，确定在原始画面中绘制的目标区域，从而，通过绘制的方式由用户自定义相应的目标区域，实现更好的防挡展示效果。
在一些实施例中，客户端响应于在原始画面中的区域绘制操作，确定该区域绘制操作对应的移动轨迹，将该移动轨迹框选出的区域确定为目标区域。例如，客户端显示多个备选图案，用户选取备选图案，基于该备选图案在原始画面中绘制目标区域，其中备选图案包括线条、矩形、圆形、三角形等图案。例如，用户需要绘制矩形的情况下，选取矩形，采用鼠标或触控方式在原始画面中移动，基于移动轨迹框选出矩形区域，将框选出的矩形区域作为目标区域；或者，用户需要绘制人形图案的情况下，由于该人形图案是不规则的图案，需要选取线条，采用鼠标或触控方式在原始画面中移动，基于移动轨迹框选出需要的人形区域，将框选出来的人形区域作为目标区域。在一些实施例中，用户在采用线条进行绘制时，绘制的移动轨迹是封闭的，或者不是封闭的，在移动轨迹不是封闭的情况下，客户端将移动轨迹的起始点和终止点采用直线连接在一起，得到封闭区域。
在一些实施例中，用户直接在原始画面中绘制目标区域。或者，客户端在原始画面上方展示空白蒙版，用户在该空白蒙版上绘制目标区域，相应的，服务端检测用户在空白蒙版中绘制的目标蒙版区域，即客户端响应于在空白蒙版中的区域绘制操作，确定在空白蒙版中绘制的目标蒙版区域，将目标蒙版区域在原始画面中对应的区域确定为目标区域。其中，空白蒙版的大小与原始画面尺寸大小相同且位置重合，用户在原始画面上方随意绘制符合自已意愿的目标蒙版区域。在一些实施例中，空白蒙版中还包含设置的非绘制区域，用户在除非绘制区域之外的绘制区域中绘制目标蒙版区域，非绘制区域用于设置用户无法指定为目标区域的区域，非绘制区域由用户在客户端中预先设置或者由服务端统一设置后下发至客户端。用户在空白蒙版中绘制的目标蒙版区域为任意形状，例如矩形、圆形、椭圆形、梯形或者不规则图形等，而且目标蒙版区域的大小由用户随意设置(如通过鼠标拖拉设置区域边界)。当然，用户能够通过触发防挡设置开关触发客户端展示空白蒙版。
在一些实施例中，客户端提供备选轮廓模板供用户选择。例如，客户端先确定用户从备选轮廓模板中选取的目标轮廓模板，并在检测到用户将目标轮廓模板放置在原始画面的展示区域中之后，将目标轮廓模板在展示区域中的对应区域确定为目标区域。也即是，客户端响应于对任一备选轮廓模板的选取操作，将选取的轮廓模板确定为目标轮廓模板，将目标轮廓模板移动至原始画面中，将原始画面中目标轮廓模板对应的区域确定为目标区域。
在一些实施例中，用户通过触发防挡设置开关控制客户端展示备选轮廓模板，然后在所展示的备选轮廓模板中选取备选轮廓模板作为目标轮廓模板，其中用户能够选取更符合自己观看意愿或目标对象的边缘轮廓形象的轮廓模板，目标对象是指用户想要实现防挡展示效果的视频画面中的展示对象。进而将目标轮廓模板直接拖动并放置在原始画面种的合适位置，例如目标对象所在位置等，从而实现对目标区域的指定。其中，目标轮廓模板为人物、食物、动物、建筑、书籍、屏幕等常见视频对象对应的对象轮廓区域，用户还能够对目标轮廓模板实施缩放操作控制其大小，本公开对此并不进行限制。通过选取轮廓模板的方式，用户只需要在所展示出的备选轮廓模板中选择更符合目标对象外形轮廓的目标轮 廓模板，然后将其通过简单地拖拉操作放置在原始画面中的相应位置并调整即可，简化了用户指定目标区域的操作步骤，提升了用户指定目标区域的效率。
在一些实施例中，客户端提供备选对象模板供用户选择。例如，客户端先确定用户从所展示的备选对象模板中选取的目标对象模板，然后检测原始画面中匹配于目标对象模板的目标对象，再将检测到的目标对象在原始画面中的对应区域确定为目标区域。也即是客户端响应于对任一备选对象模板的选取操作，将选取的备选对象模板确定为目标对象模板，响应于原始画面中具有匹配于目标对象模板的目标对象，将原始画面中目标对象对应的区域确定为目标区域。
在一些实施例中，用户通过触发防挡设置开关控制客户端展示备选对象模板，然后在客户端展示的备选对象模板中选取目标对象模板。其中，根据目标对象模板确定出的目标对象即为用户感兴趣的想要实现防挡展示效果的视频对象。通过选取对象模板的方式，客户端能够根据用户指定的目标对象模板确定相应的目标对象。或者，客户端为用户展示目标对象选取控件，从而由用户在当前视频画面中自定义选取相应的目标对象，以避免备选对象模板中不存在目标对象时用户无法选取的问题。通过选取目标对象的方式，客户端能够通过对目标视频的本地实时检测实现目标对象的高效准确识别，从而实现对目标视频中目标对象的动态跟踪，进而实现针对目标对象的动态防挡展示效果。
在一些实施例中，为减轻客户端识别目标对象时的运算压力，客户端向服务端请求获取对应于用户选取的目标对象模板的目标对象，即由服务端根据目标对象模板确定目标对象。例如，客户端先确定用户从备选对象模板中选取的目标对象模板，然后将目标对象模板和原始画面对应的画面图像提供至服务端，最后接收服务端返回的目标区域的区域坐标。也即是，客户端响应于对任一备选对象模板的选取操作，将选取的备选对象模板确定为目标对象模板，向服务器发送目标对象模板和原始画面对应的画面图像，接收服务端返回的区域坐标，基于该区域坐标确定目标区域。其中，目标区域对应于画面图像中的目标对象，该目标对象匹配于目标对象模板。
类似的，用户通过触发防挡设置开关控制客户端展示备选对象模板，然后在客户端展示的备选对象模板中选取对应于目标对象的目标对象模板。其中，原始画面对应的画面图像为当前视频帧图像；或者画面图像为当前视频帧图像的图像快照；或者为减轻与服务端之间的数据传输压力，画面图像为当前视频帧图像的视频帧标识(如帧图像序号等)，相应的，服务端根据该视频帧标识在本地保存的目标视频中确定相应的视频帧图像，本公开对此并不进行限制。另外，目标区域的区域坐标为目标区域轮廓线中各个像素点的像素点坐标。通过上述方式，将运算量较大的对象识别与匹配任务交由服务端完成，从而不仅减小了客户端的运算压力，而且能够充分发挥服务端的运算优势，有助于减少客户端的播放卡顿。
步骤304，将目标区域中的弹幕图层调整至画面图层下方。
原始画面根据画面图层和位于画面图层上方的弹幕图层渲染得到，因此，在确定目标区域后，客户端将位于目标区域中的弹幕图层调整至画面图层下方，而目标区域之外的其他区域则不进行上述调整。
在一些实施例中，弹幕图层和画面图层具有对应的层级，层级高的图层位于层级低的图层的上方。客户端确定目标区域之后，将目标区域中的弹幕图层的层级调整至低于画面图层的层级，基于画面图层的层级和目标区域中调整后的弹幕图层的层级，将目标区域中的弹幕图层调整至画面图层下方。
步骤306，根据调整后的画面图层绘制并展示对应于目标区域的目标画面。也即是基于目标区域中调整后的画面图层，渲染对应于目标区域的目标画面，展示该目标画面。
在本公开的实施例中，客户端根据目标区域中调整后的画面图层(即位于最上方的图 层)，渲染对应于目标区域的目标画面，渲染过程参见相关技术中渲染画面元素以及页面渲染的相关内容，此处不再赘述。
在一些实施例中，客户端确定原始画面中区别于目标区域的其他区域，然后将其他区域的原始画面与目标画面拼接为视频画面，并展示该视频画面。其中，其他区域可称为第一区域。此时，经过上述过程展示出的视频画面中，目标画面仅展示画面内容，而不展示相应的弹幕；而其他区域对应的原始画面中同时展示画面内容和相应的弹幕，弹幕仍然会对画面内容产生遮挡，从而实现对于目标区域中画面内容的针对性防挡展示效果。
在一些实施例中，客户端是基于HTML5(Hyper Text Markup Language，第五代超文本标记语言)技术搭建的，相应的，原始画面和目标画面能够在HTML5页面中展示，此时，客户端基于目标区域中调整后的画面图层，使用HTML5页面的原生画布功能(如canvas画布等)渲染目标画面，在该HTML5页面中展示该目标画面。从而充分发挥HTML5页面的原生画布技与HTML5页面的兼容性及适配程度较高的技术优势，渲染过程参见相关技术中的记载，此处不再赘述。
根据本公开的实施例，由客户端响应于用户针对原始画面实施的区域指定操作，进而确定需要防挡的目标对象和相应的防挡区域，从而改进所展示视频画面及其相应弹幕的展示效果。
相应的，本公开还提出了服务端侧的视频画面的展示方法。图4是根据本公开的实施例示出的另一种视频画面的展示方法的流程图。如图4所示，该方法应用于服务端，包括以下步骤：
步骤402，接收客户端提供的目标对象模板和原始画面对应的画面图像，目标对象模板是从备选对象模板中选取的。
步骤404，确定画面图像中匹配于目标对象模板的目标对象。
步骤406，向客户端返回目标区域的区域坐标，该目标区域为目标对象在原始画面中所对应的区域，客户端用于将目标区域中的弹幕图层调整至画面图层下方，基于目标区域中调整后的画面图层渲染并展示对应于目标区域的目标画面。
在一些实施例中，服务端先识别画面图像中的所有画面对象，然后依次确定各个画面对象与目标对象模板之间的匹配度，再根据各个画面对象对应的匹配度，确定目标对象。即服务端将匹配度最高的画面对象，确定为目标对象；或者将匹配度高于匹配度阈值的画面对象，确定为目标对象。其中，画面对象是指画面图像中的对象，原始画面对应的画面图像为当前视频帧图像；或者画面图像为当前视频帧图像的图像快照；或者画面图像为当前视频帧图像的视频帧标识(如帧图像序号等)，相应的，服务端根据该视频帧标识在本地保存的目标视频中，确定相应的视频帧图像，本公开对此并不进行限制。通过上述识别及匹配过程，服务端能够确定出视频画面中的至少一个目标对象，并将各个目标对象所对应目标区域的区域坐标返回至客户端，从而充分发挥自身的运算优势，以减轻客户端的运算压力。
另外，在识别出的所有画面对象对应的匹配度均不高于匹配度阈值的情况下，服务端向客户端返回匹配失败消息，该匹配失败消息指示画面图像中不存在目标对象。相应的，客户端在接收到匹配失败消息后不进行图层调整，而直接展示原始画面即可。此时所展示的视频画面并不存在防挡区域，即此时并未产生防挡展示效果。
因为目标视频由多张视频帧图像组成，所以展示目标视频的过程即为依次展示各张视频帧图像的过程。实际上，上述图3和图4所示实施例的处理过程，为客户端或服务端针对当前时刻正在展示的视频帧图像的处理过程，当然，为实现接近实时的防挡展示效果，客户端或服务端识别目标对象时，识别视频画面中目标时刻对应的视频帧图像，该目标时刻为位于当前时刻之后、且与当前时刻间隔第一时长的时刻，第一时长为任一时长，从而到 达目标时刻后即可实时展示具有防挡展示效果的目标画面。
下面结合图5-图10所示实施例，对上述视频画面的展示方法进行详细说明。图5是根据本公开的实施例示出的又一种视频画面的展示方法的流程图。如图5所示，该方法应用于客户端，该方法对应的视频画面的渲染及展示过程包括以下步骤：
步骤502，检测到用户打开防挡设置开关。
在一些实施例中，客户端在目标视频的视频展示界面中展示防挡设置开关，因此用户能够在视频展示界面中触发该防挡设置开关，以控制开始在原始画面中指定防挡区域。
如图6所示，对于目标视频(如视频V)对应的视频展示界面611，在其对应的弹幕开关614处于打开状态的情况下，视频展示界面611中展示有画面内容612和弹幕613，视频展示界面611下方还展示有防挡设置开关615。当然，图6所示的“防挡设置”仅是示例性的，该开关在实际展示时能够展示为其他名称，本公开对此并不进行限制。
步骤504，在原始画面上方展示空白蒙版。
在一些实施例中，在目标视频处于播放状态或暂定状态的情况下，客户端对应的用户(目标视频的观众)通过触发防挡设置开关615打开该防挡设置开关。如图6所示，在防挡设置开关623处于打开状态的情况下，检测到防挡设置开关被触发时，客户端在视频展示界面611上方展示空白蒙版621，该空白蒙版621为半透明形式，透明度由用户在客户端中设置或者采用客户端或服务端的系统设置。
步骤506，检测用户实施的区域绘制操作。
透过半透明形式的空白蒙版621，用户观察到空白蒙版621下方展示的原始画面的画面内容，进而通过鼠标或触摸控制在该空白蒙版621中的响应位置绘制目标蒙版区域622。
如图6所示，用户在原始画面中某人像上方的空白蒙版621中绘制矩形的目标蒙版区域622。实际上，用户能够随意调整目标蒙版区域622的位置、大小、角度等参数，例如，目标蒙版区域622的形状为矩形、圆形、椭圆形、梯形或者不规则图形等，目标蒙版区域的大小由用户通过鼠标拖拉区域边界进行任意调整，本公开对于目标蒙版区域的样式及绘制方式并不进行限制。
在一些实施例中，在用户绘制目标蒙版区域622的过程中，客户端展示实时的防挡预览效果，以便用户根据该预览效果适当调整目标蒙版区域622的起点、大小、角度等位置参数，从而实现更佳的防挡展示效果。用户在空白蒙版621中绘制若干个目标蒙版区域622，当绘制完毕后，用户触发(如单击)确认控件624，客户端响应于对确定控件624的触发操作，确定目标蒙版区域622绘制完毕。
步骤508，确定用户绘制的目标蒙版区域对应的目标区域。
客户端在检测到用户针对确认控件实施的触发操作之后，确定用户所绘制的目标蒙版区域在原始画面中对应的目标区域，确定目标区域的过程，即为确定目标区域在原始画面中的区域坐标的过程。例如，在用户直接在原始画面中绘制目标区域的情况下，目标区域的实际位置即为其在原始画面中的位置。
又例如，在空白蒙版与原始画面尺寸相同且覆盖在原始画面上方(如图6所示)的情况下，因为空白蒙版与原始画面完全对应，所以可将目标蒙版区域在空白蒙版中的区域坐标作为目标区域在原始画面中的区域坐标；而在空白蒙版与原始画面并不完全对应的情况下，先确定目标蒙版区域在空白蒙版中的区域坐标，然后根据空白蒙版相对于原始画面的坐标偏移量和/或缩放量相应计算目标区域在原始画面中的区域坐标，具体过程不再赘述。
步骤510，将目标区域中的弹幕图层调整至画面图层下方。
因为原始画面根据画面图层和位于画面图层上方的弹幕图层渲染得到，所以要实现对画面内容的防挡展示效果，在确定目标区域后，客户端将位于目标区域中的弹幕图层调整至画面图层下方，而目标区域之外的其他区域则不进行上述调整。
步骤512，渲染对应于目标区域的目标画面。
在本公开的实施例中，客户端根据目标区域中调整后的画面图层(即位于最上方的图层)，渲染对应于目标区域的目标画面，渲染目标画面的过程参见相关技术中记载的渲染画面元素以及页面渲染的相关内容，此处不再赘述。另外，客户端确定原始画面中区别于目标区域的第一区域，然后将第一区域的原始画面与目标画面拼接为视频画面。实际上，上述渲染目标区域所对应目标画面的过程，与渲染第一区域的原始画面的过程是同时进行的，即二者并非独立进行，而是构成一个完整的视频画面渲染过程。
在一些实施例中，客户端渲染目标区域中调整后的画面图层和弹幕图层，得到目标区域的目标画面；或者，由于目标区域中的弹幕图层位于画面图层的下方，即使渲染目标区域中的弹幕图层，渲染得到的弹幕在目标区域中也会被遮挡，因此，客户端能够仅渲染目标区域中的画面图层，得到目标区域的目标画面。
在一些实施例中，客户端是基于HTML5技术搭建的，相应的，原始画面和目标画面在HTML5页面中展示，此时，使用HTML5技术提供的原生的canvas画布渲染上述目标画面，渲染过程参加相关技术中的记载，此处不再赘述。
步骤514，展示目标画面。
渲染完成后，在目标视频对应的视频展示界面中展示渲染得到的目标画面。可以理解的是，和渲染目标画面的过程类似，展示目标视频的过程与展示第一区域对应的视频画面也是同时进行的，即客户端对二者构成的视频画面进行展示，而并非单独展示目标画面与第一区域对应的原始画面。
如图6所示，视频展示界面632中展示有目标区域对应的目标画面631，该区域中仅展示画面内容(如画面中的人像)而不展示相应的弹幕，而在区别于目标区域的第一区域中同时展示画面内容和弹幕633。在视频画面播放过程中，移动播放的弹幕进入目标区域后自动被隐藏，类似于被遮挡在目标画面下方而无法观察到，从而实现对目标区域中画面内容的防挡展示效果。
经过上述过程展示出的视频画面中，目标画面仅展示画面内容，而不展示相应的弹幕；而第一区域对应的视频画面中同时展示画面内容和相应的弹幕，弹幕仍然会对画面内容产生遮挡，从而实现对于目标区域中画面内容的针对性防挡展示效果。
图7是根据本公开的实施例示出的再一种视频画面的展示方法的示意图，如图7所示，该方法应用于客户端，该方法对应的视频画面的渲染及展示过程包括以下步骤：
步骤702，检测到用户打开防挡设置开关。
在一些实施例中，客户端在目标视频的视频展示界面中展示防挡设置开关，因此用户在视频展示界面中触发该防挡设置开关，以开始在原始画面中指定防挡区域。
在检测到防挡设置开关被触发开启的情况下，客户端展示相应的设置方式选择控件，以由用户选择进行防挡设置的方式。例如，用户选择通过区域设置的方式设置防挡区域，然后执行步骤7041；或者用户选择通过对象设置的方式设置防挡区域，然后执行步骤7042。
步骤7041，展示备选轮廓模板。
在检测到用户选择通过区域设置的方式设置防挡区域的情况下，客户端向用户展示备选轮廓模板，供用户选择对应于目标对象的目标轮廓模板，该目标对象是指用户想要实现防挡展示效果的画面对象。
如图8所示，在防挡设定开关803处于开启状态的情况下，客户端在目标视频(视频V)对应的视频展示界面上方展示轮廓模板选取界面802，该轮廓模板选取界面802中包含至少一个备选轮廓模板。展示出的备选轮廓模板对应于多种对象，例如对应于女士正脸轮廓的备选轮廓模板A、对应于男士侧脸轮廓的备选轮廓模板B、对应于餐具(盘子)轮 廓的备选轮廓模板C、对应于打开的书籍轮廓的备选轮廓模板D等。上述备选轮廓模板集成在客户端的安装程序中，从而在客户端安装完毕后，即可展示各个备选轮廓模板；或者，为保证模板的及时更新，在展示目标视频之前或者展示目标视频的过程中从服务端获取各个备选轮廓模板；上述备选轮廓模板由服务端根据视频库中的海量视频通过模型算法提取得到。在一些实施例中，对备选轮廓模板进行分类，并根据目标视频所属类别提供相应的备选轮廓模板，不再赘述。
步骤7061，确定用户选取的目标轮廓模板。
步骤7081，检测用户的放置操作。
用户在展示出的多个备选轮廓模板中选取目标轮廓模板，例如通过鼠标点击、触控操作等方式进行选取。如图8所示，在用户想要实现防挡展示效果的目标对象为原始画面中所示的女士正脸801的情况下，用户选择备选轮廓模板中与该女士正脸对应的人脸轮廓形状相似的备选轮廓模板A，即将备选轮廓模板A作为目标轮廓模板，并直接拖动该目标轮廓模板A至原始画面的相应位置，然后通过拖拉轮廓模型边界的方式将该目标轮廓模板A的大小和位置调整至覆盖女士正脸801，以达到较佳的防挡展示效果。其中，在用户拖动备选轮廓模板A之后，轮廓模板选取界面802可直接隐藏。当然，用户也能够选择其他备选轮廓模板作为目标轮廓模板，调整方式以用户实际操作为准，本公开对此并不进行限制。
步骤7101，确定放置后的目标轮廓模板在原始画面中的放置区域。
进一步的，客户端通过检测放置操作，确定放置后的目标轮廓模板，进而确定该目标轮廓模板在原始画面中的放置区域。该放置区域通过目标轮廓模板的区域边界在原始画面中对应的各个像素点的坐标值来表示，当然，在目标轮廓模板的轮廓边界为标准形状的情况下，也能够通过该目标轮廓模板的中心点坐标和模板尺寸等特征来表示，本公开对此并不进行限制。
步骤7042，展示备选对象模板。
在检测到用户选择通过对象设置的方式设置防挡区域的情况下，客户端向用户展示备选对象模板，以供用户选择对应于目标对象的目标对象模板，该目标对象是指用户想要实现防挡展示效果的画面对象。
如图9所示，在防挡设定开关903处于开启状态的情况下，客户端在目标视频(视频V)对应的视频展示界面上方展示对象模板选取界面902，该对象模板选取界面902中包含至少一个备选对象模板，展示出的备选对象模板对应于多种对象，例如对应于人物的备选对象模板A、对应于食物的备选对象模板B、对应于动物的备选对象模板C、对应于打开的书籍的备选对象模板D等。上述备选对象模板集成在客户端的安装程序中，从而在客户端安装完毕后即可展示各个备选对象模板；或者，为保证模板的及时更新，在展示目标视频之前或者展示目标视频的过程中从服务端获取备选对象模板；上述备选对象模板由服务端根据视频库中的海量视频中提取得到。在一些实施例中，对备选对象模板进行分类，并根据目标视频所属类别提供相应的备选对象模板，不再赘述。
步骤7062，确定用户选取的目标对象模板。
用户在展示出的若干个备选对象模板中选取目标对象模板，例如通过鼠标点击、触控操作等方式进行选取。如图9所示，用户想要实现防挡展示效果的目标对象为原始画面中所示的女士正脸901的情况下，用户选取备选对象模板中对应于人物的备选对象模板A。用户选取至少一个备选对象模板作为目标对象模板，并在选取完成后触发相应的确定控件904，从而将选取的备选对象模板确定为目标对象模板。
步骤7082，检测画面图像中的画面对象。
客户端先确定当前时刻的画面图像，例如，将当前时刻的视频帧图像作为画面图像； 或者对当前时刻的视频帧图像实施画面快照，并将得到的快照图像作为画面图像；或者，为实现接近实时的防挡展示效果，将目标时刻对应的视频帧图像或快照图像确定为画面图像。其中，目标时刻为位于当前时刻之后、且与当前时刻间隔第一时长的时刻，第一时长为任一时长。
进一步的，通过对象识别算法对画面图像进行处理，从而识别出画面图像中的画面对象。例如，采用相关技术中的聚类算法、深度学习算法实现，当然也能够采用自定义的图像识别模型识别上述画面对象，不再赘述。
步骤7102，确定画面对象中匹配于目标对象模板的目标对象。
在识别出画面图像中的画面对象后，客户端依次计算各个画面对象与目标对象模板之间的匹配度，例如通过颜色、轮廓、运动轨迹等多种特征参数计算上述匹配度。可以理解的是，任一画面对象的特征参数与目标对象模板的特征参数越接近，则该画面对象与目标对象模板之间的匹配度越高，即画面对象与目标对象模板之间的匹配度与二者所对应特征参数之间的接近程度呈正相关。进而，将匹配度最高的画面对象或者匹配度高于匹配度阈值的画面对象确定为目标对象；当然，在所有画面对象的匹配度均低于匹配度阈值的情况下，则表明当前画面图像中并不存在目标对象，此时客户端直接结束本次处理过程，不再针对当前视频帧图像进行后续处理，开始进行针对下一视频帧图像的处理过程。
步骤712，确定目标对象在原始图像中对应的目标区域。
确定目标区域的过程，即为确定目标区域对应的区域坐标的过程。对应于上述步骤7041-7101，客户端直接将放置区域的区域坐标确定为目标区域的区域坐标。对应于上述步骤7042-7102，客户端将目标对象在原始画面中的对象轮廓对应的轮廓坐标确定为目标区域的区域坐标。
步骤714，将目标区域中的弹幕图层调整至画面图层下方。
步骤716，渲染对应于目标区域的目标画面。
步骤718，展示目标画面。
上述步骤714-718与前述图5所示实施例中步骤510-514并不存在本质区别，因此步骤714-718的实施过程参见前述记载，此处不再赘述。
实际上，对应于上述步骤510-514的实施例，识别画面对象并确定目标对象的步骤，也能够由服务端执行，下面结合图10进行说明。图10是根据本公开的实施例示出的一种视频画面的展示方法的交互流程图，如图10所示，上述渲染目标区域对应的目标画面并进行展示的过程包括下述步骤：
步骤1002，客户端检测到用户打开防挡设置开关。
步骤1004，客户端展示备选对象模板。
步骤1006，客户端确定用户选取的目标对象模板。
步骤1008，客户端确定画面图像。
上述步骤1002-1008与前述图7所示实施例中步骤702-7062并不存在本质区别，因此步骤1002-1008的实施过程参见前述记载，此处不再赘述。
步骤1010，客户端将目标对象模板和画面图像关联提供至服务端。
步骤1012，服务端检测画面图像中的画面对象。
步骤1014，服务端确定画面对象中的目标对象。
步骤1016，服务端确定原始画面中的目标区域。
步骤1018，服务端将目标区域的区域坐标返回至客户端。
确定目标对象模板和画面图像后，客户端将目标对象模板和画面图像提供至服务端，相应的，服务端通过对象识别算法检测画面图像中的画面对象，并通过匹配度计算确定画面对象中的目标对象，最后确定目标对象在原始画面中的目标区域，并将目标区域的区域 坐标返回至客户端。上述识别、匹配的过程参见前述步骤7062-712的记载，此处不再赘述。
步骤1020，客户端将目标区域中的弹幕图层调整至画面图层下方。
步骤1022，客户端渲染对应于目标区域的目标画面。
步骤1024，客户端展示目标画面。
上述步骤1020-1024与前述图5所示实施例中步骤510-514并不存在本质区别，因此步骤1020-1024的实施过程参见前述记载，此处不再赘述。
通过上述过程，由服务端进行运算量较大的对象识别和匹配计算，不仅有助于充分发挥自身的运算优势，而且能够减轻客户端的运算压力，一定程度上避免客户端卡顿。
在一些实施例中，上述视频画面的展示方法能够应用于直播场景下。例如，用户在基于直播应用客户端观看直播时，为了避免直播间中的其他用户发送的弹幕遮挡主播，能够采用上述视频画面的展示方法，确定直播视频的直播画面中主播对应的目标区域，将该目标区域中的弹幕图层调整至画面图层下方，基于目标区域调整后的画面图层，渲染对应于目标区域的目标画面，展示目标画面，使目标画面中显示主播而不显示弹幕。
