技术领域
本公开涉及视频的处理技术领域，具体而言，本公开涉及一种视频的处理方法、装置、电子设备及非暂时性计算机可读存储介质。
背景技术
传统的绿幕技术，是指影视拍摄时使用纯色(最好是绿色)的布作为演员的背景，方便后期制作时将人像扣出，放置到其他背景上，合成成片。后来专业编辑软件不局限于影视从业者使用，影视剪辑爱好者也可以利用Adobe Premiere等专业软件将人物用钢笔或吸管等工具抠出，并叠加在其他背景上。但这种类型的绿幕技术都有两个问题，显著地提高了用户在日常中拍摄视频时的使用门槛：
第一，它要求人物身后有绿幕，或者背景与人物的色彩反差明显，对于身后色彩丰富混杂的场景无法轻易处理。
第二，它要求剪辑者有一定的软件知识，并在视频拍好后进行后期编辑，较为繁杂，难以掌握。
发明内容
提供本公开以便以简要的形式介绍构思，这些构思将在后面的具体实施方式部分被详细描述。本公开并不旨在标识要求保护的技术方案的关键特征或必要特征，也不旨在用于限制所要求的保护的技术方案的范围。

第三方面，提供了一种电子设备，该电子设备包括：
处理器、存储器和总线；
所述总线，用于连接所述处理器和所述存储器；
所述存储器，用于存储操作指令；
所述处理器，用于通过调用所述操作指令，可执行指令使处理器执行如本公开的第一方面所示的视频的处理方法对应的操作。
第四方面，提供了一种非暂时性计算机可读存储介质，该非暂时性计算机可读存储介质上存储有计算机程序，该程序被处理器执行时实现本公开第一方面所示的视频的处理方法。
本公开提供的技术方案带来的有益效果是：

下面以具体地实施例对本公开的技术方案以及本公开的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本公开的实施例进行描述。
在一个实施例中提供了一种视频的处理方法，如图1所示，该方法包括：
步骤S101，当预设的应用程序进入拍摄模式时，在应用程序的当前界面中展示预设的拍摄界面；拍摄界面具有预设的初始背景；
具体而言，应用程序可以预设有拍摄模式，当应用程序处于拍摄模式时，应用程序可以调用终端上的图像采集设备、音频采集设备等来采集图像、音频等数据。其中，预设的拍摄界面可以设置有初始背景，初始背景可以是视频背景，也可以是图像背景，当应用程序展示拍摄界面时，就会在拍摄界面中展示初始背景。
步骤S102，获取目标对象的图像帧和初始背景；
通常来说，应用程序在加载拍摄界面的时候，可以从预设的视频背景资源库中获取初始背景并展示在拍摄界面中，同时，获取目标对象的图像帧，比如，人物对象的图像帧。
步骤S103，将图像帧作为前景与初始背景结合，并在拍摄界面中进行展示；
在获取到了目标对象的图像帧和初始背景之后，可以将目标对象的图像帧作为前景，将初始背景作为背景，在拍摄界面中同时展示图像帧和初始背景。
步骤S104，当接收到第一开始拍摄指令时，基于图像帧和初始背景开始生成视频数据；
步骤S105，当接收到第一结束拍摄指令时，停止生成视频数据，得到已生成的第一视频数据。
具体而言，当用户触发了开始拍摄指令后，应用程序就可以基于图像帧和初始背景开始生成视频数据，然后将生成的视频数据进行存储，当用户触发了结束拍摄指令后，应用程序就可以停止生成视频数据，从而得到一段视频数据。
在本公开实施例中，当预设的应用程序进入拍摄模式时，在应用程序的当前界面中展示预设的拍摄界面；拍摄界面具有预设的初始背景，然后获取目标对象的图像帧和初始背景，将图像帧作为前景与初始背景结合，并在拍摄界面中进行展示；当接收到第一开始拍摄指令时，基于图像帧和初始背景开始生成视频数据，当接收到第一结束拍摄指令时，停止生成视频数据，得到已生成的第一视频数据。这样，用户在日常拍摄视频的过程中，不管用户的背景是否为纯色或接近纯色，都可实现自动地将目标对象与用户需求的背景相结合，减少了用户的大量手动操作，提升了用户体验。而且，用户通过简单的操作即可进入本申请提供的拍摄模式，交互路径快捷方便，不需要用户经过多次界面或者功能的切换，进一步提升了用户体验。
在一个实施例中提供了一种视频的处理方法，如图2所示，该方法包括：
步骤S201，当预设的应用程序进入拍摄模式时，在应用程序的当前界面中展示预设的拍摄界面；拍摄界面具有预设的初始背景；
具体而言，应用程序可以安装在终端中，终端可以具有如下特点：
(1)在硬件体系上，设备具备中央处理器、存储器、输入部件和输出部件，也就是说，设备往往是具备通信功能的微型计算机设备。另外，还可以具有多种输入方式，诸如键盘、鼠标、触摸屏、送话器和摄像头等，并可以根据需要进行调整输入。同时，设备往往具有多种输出方式，如受话器、显示屏等，也可以根据需要进行调整；
(2)在软件体系上，设备必须具备操作***，如Windows Mobile、Symbian、Palm、Android、iOS等。同时，这些操作***越来越开放，基 于这些开放的操作***平台开发的个性化应用程序层出不穷，如通信簿、日程表、记事本、计算器以及各类游戏等，极大程度地满足了个性化用户的需求；
(3)在通信能力上，设备具有灵活的接入方式和高带宽通信性能，并且能根据所选择的业务和所处的环境，自动调整所选的通信方式，从而方便用户使用。设备可以支持GSM(Global System for Mobile Communication，全球移动通信***)、WCDMA(Wideband Code Division Multiple Access，宽带码分多址)、CDMA 2000(Code Division Multiple Access，码分多址)、TDSCDMA(Time Division-Synchronous Code Division Multiple Access，时分同步码分多址)、Wi-Fi(Wireless-Fidelity，无线保真)以及WiMAX(Worldwide Interoperability for Microwave Access，全球微波互联接入)等，从而适应多种制式网络，不仅支持语音业务，更支持多种无线数据业务；
(4)在功能使用上，设备更加注重人性化、个性化和多功能化。随着计算机技术的发展，设备从“以设备为中心”的模式进入“以人为中心”的模式，集成了嵌入式计算、控制技术、人工智能技术以及生物认证技术等，充分体现了以人为本的宗旨。由于软件技术的发展，设备可以根据个人需求调整设置，更加个性化。同时，设备本身集成了众多软件和硬件，功能也越来越强大。
进一步，该应用程序可以预设有拍摄模式，当应用程序处于拍摄模式时，应用程序可以调用终端上的图像采集设备、音频采集设备等来采集图像、音频等数据。
具体地，用户在终端中启动应用程序后，可以通过触发指定的指令使得应用程序进入拍摄模式，比如，如图3所示，在应用程序的初始界面301中设置一个可以进入拍摄模式的按钮302，当用户点击了这个按钮，即触发了进入拍摄模式的指令，这样应用程序就会进入拍摄模式，然后展示预设的拍摄界面了。其中，预设的拍摄界面可以设置有初始背景，初始背景可以是视频背景，也可以是图像背景，当应用程序展示拍摄界面时，就会在拍摄界面中展示初始背景。
如图4所示，在预设的拍摄界面中，可以包括拍摄按钮401、展示/关闭背景预览窗口的按钮402、背景预览窗口403、功能区404、拍摄进度条405、退出拍摄界面的按钮406、以及音频管理按钮407。在实际应用中，如果拍摄界面中已经展示了预览窗口(如图4所示)，那么当用户点击了按钮402后，背景预览窗口就会被关闭，如图5所示；如果拍摄界面中没有展示预览窗口，那么当用户点击了按钮402后，就会在拍摄界面中展示背景预览窗口(如图4所示)。其中，功能区可以包括多个辅助拍摄的功能按钮；背景预览窗口用于展示替换初始背景的候选背景，候选背景包括图像背景和视频背景，在展示视频背景时，可以展示该视频背景的时长；背景预览窗口中的“+”可以是本地存储的接口，当用户点击“+”时，即可展示本地存储的视频背景和图像背景，如图6所示。
进一步，在实际应用中，在应用程序的初始界面中，点击按钮302可以进入到拍摄界面，还可以在拍摄界面中设置其它模式的标识，比如在拍摄界面的最下方设置“拍照模式”、“普通拍摄模式”等其它模式的标识(图中未示出)，当用户点击了不同的标识时，即可进入对应的模式。在实际应用中可以根据实际需求进行设置，本公开实施例对此不作限制。
其中，“拍照模式”可以用于拍摄照片，“普通拍摄模式”可以用于拍摄无背景、无特效等的普通视频。
进一步，在应用程序的初始界面中，通过点击按钮302可以默认进行本申请中的拍摄模式，也可以默认进入“拍照模式”或“普通拍摄模式”，然后由用户切换至本申请中的拍摄模式。在实际应用中可以根据实际需求进行设置，本公开实施例对此也不作限制。
步骤S202，获取目标对象的图像帧和初始背景；
通常来说，应用程序在加载拍摄界面的时候，可以从预设的视频背景资源库中获取初始背景并展示在拍摄界面中，同时，获取目标对象的图像帧，比如，人物对象的图像帧。
根据本公开的实施例，获取目标对象的图像帧，包括：
通过预设的图像采集设备获取图像帧；以及
当检测到图像帧中目标对象时，从图像帧中提取出目标对象，得到目 标对象的图像帧。
具体而言，应用程序在加载拍摄界面的时候，也会调用终端中的图像采集设备，并通过图像采集设备来获取图像帧，然后通过预设的目标对象检测模型检测图像帧中是否包含目标对象，比如人物对象，如果包含目标对象，则从图像帧中提取出目标对象。比如，图像采集设备获取到的图像帧可以如图7A所示，检测到图像帧中包含人物对象，因此从图像帧中提取出人物对象，得到如图7B所示的人物对象的图像帧。其中，在提取目标对象时，目标对象的背景可以是任意背景，不需要纯色背景或接近纯色的背景。
需要说明的是，提取目标对象的过程可以展示给用户，也可以不展示给用户，也就是说，用户可以直接看到目标对象的图像帧，也可以先展示图像帧，然后再提取目标对象，并展示目标对象的图像帧，在实际应用中可以根据实际需求进行设置，本公开实施例对此不作限制。
进一步，提取目标对象除了可以采用上述方式之外，其它的提取方式也是适用于本公开实施例的，在实际应用中可以根据实际需求进行设置，本公开实施例对此也不作限制。
步骤S203，将图像帧作为前景与初始背景结合，并在拍摄界面中进行展示；
在获取到了目标对象的图像帧和初始背景之后，可以将目标对象的图像帧作为前景，将初始背景作为背景，在拍摄界面中同时展示图像帧和初始背景，如图8所示。
步骤S204，当接收到第一开始拍摄指令时，基于图像帧和初始背景开始生成视频数据；
步骤S205，当接收到第一结束拍摄指令时，停止生成视频数据，得到已生成的第一视频数据；
具体而言，当用户触发了开始拍摄指令后，应用程序就可以基于图像帧和初始背景开始生成视频数据，生成视频时的界面可以如图9所示，然后将生成的视频数据进行存储，当用户触发了结束拍摄指令后，应用程序就可以停止生成视频数据，从而得到一段视频数据。
进一步，用户触发开始拍摄指令可以是用户点击一下拍摄按钮，用户触发结束拍摄指令可以是用户再次点击一下拍摄按钮；或者，也可以是用户通过点击并持续按压拍摄按钮来触发开始拍摄指令并生成视频数据，用户松开拍摄按钮则触发结束拍摄指令。当然，用户通过其它的控制方式来触发开始拍摄指令和结束拍摄指令也是适用于本公开实施例的，比如，通过语音控制、手势控制等等，在实际应用中可以根据实际需求进行设置，本公开实施例对此不作限制。
步骤S206，当接收到针对任一候选背景的选择指令时，基于任一候选背景得到目标候选背景；
当用户点击了背景预览窗口中的任一候选背景时，应用程序可以基于该候选背景确定出目标候选背景。
根据本公开的实施例，任一候选背景为视频背景，基于任一候选背景得到目标候选背景，包括：
展示预设的视频编辑界面，并在视频编辑界面中展示视频背景；
接收针对视频背景的编辑指令，并响应于编辑指令对视频背景进行编辑，得到编辑后的视频背景预览；
当接收到针对编辑后的视频背景预览的确认指令时，得到编辑后的视频背景，作为目标候选背景。
具体而言，如果用户选择的候选背景是视频背景，那么可以在应用程序中展示预设的视频编辑界面，并在视频编辑界面中展示该视频背景，如图10所示，视频编辑界面中可以包括视频帧选择框1001、已选择的视频帧的时长1002、静音按钮1003、旋转按钮1004、返回按钮1005、以及确认按钮1006。
在编辑界面中，用户可以通过拖动视频帧选择框来选择出视频背景中的一段视频，视频帧选择框里展示的就是这一段视频的视频背景预览，已选择的视频帧的时长就是这一段视频的时长，然后用户点击确认按钮即可将这一段视频作为目标候选背景。而且，用户还可以点击静音按钮、旋转按钮来进行相应的调整。
如果选择的候选背景是图像背景，那么可以直接将该候选背景作为目 标候选背景，也可以先对图像背景进行编辑，比如裁剪、调色等等，然后将编辑完成的图像背景作为目标候选背景。
步骤S207，采用目标候选背景替换拍摄界面中的初始背景；
步骤S208，将图像帧作为前景与目标候选背景结合，并在拍摄界面中进行展示；
当用户点击了编辑界面中的确认按钮之后，即可在拍摄界面中采用目标候选背景替换初始背景，并将目标候选背景作为背景，图像帧作为前景，在拍摄界面中展示目标候选背景和图像帧。比如，对图8所示的拍摄界面进行背景替换，可以得到如图11所示的拍摄界面。
步骤S209，当接收到第二开始拍摄指令时，基于图像帧和目标候选背景开始生成视频数据；
步骤S2010，当接收到第二结束拍摄指令时，停止生成视频数据，得到已生成的第二视频数据；
步骤S2011，当接收到完成拍摄指令时，退出拍摄模式，并将第一视频数据与第二视频数据进行拼接，得到最终的目标视频数据。
通常来说，用户替换了背景之后会继续拍摄视频，拍摄视频的原理可参照步骤S204～步骤S205，在此就不赘述了。
进一步，如图12所示，拍摄进度条可以展示已拍摄的视频的时长，如果拍摄了多段视频，那么进度中各段视频之间可以设置结点1201进行标记，同时，拍摄界面中还可以展示重新拍摄按钮1202以及完成拍摄按钮1203。当用户点击了重新拍摄按钮时，即可在如图8所示的拍摄界面中重新进行拍摄；当用户点击了完成拍摄按钮时，即可退出拍摄模式，并将用户已拍摄的至少一段视频数据进行拼接，得到最终的目标视频数据。
需要说明的是，本公开实施例中的两段视频数据仅仅只是为了举例说明，在实际应用中，用户可以拍摄多段视频数据，并非只能拍摄两段视频数据，本公开实施例对此不作限制。
在本公开实施例中，当预设的应用程序进入拍摄模式时，在应用程序的当前界面中展示预设的拍摄界面；拍摄界面具有预设的初始背景，然后获取目标对象的图像帧和初始背景，将图像帧作为前景与初始背景结合， 并在拍摄界面中进行展示；当接收到第一开始拍摄指令时，基于图像帧和初始背景开始生成视频数据，当接收到第一结束拍摄指令时，停止生成视频数据，得到已生成的第一视频数据。这样，在用户在日常拍摄视频的过程中，不管用户的背景是否为纯色或接近纯色，都可实现自动地将目标对象与用户需求的背景相结合，减少了用户的大量手动操作，提升了用户体验。而且，用户通过简单的操作即可进入本申请提供的拍摄模式，交互路径快捷方便，不需要用户经过多次界面或者功能的切换，进一步提升了用户体验。
而且，不仅可以支持图像背景、视频背景，还支持分段拍摄，在拍摄完成时，可以将多段不同背景的视频自动合成一个完成视频，这样，一个完成视频中既包含了多个背景，提升了视频的趣味性，又不需要用户手动对各段视频进行合成，减少了用户的手动操作，进一步提升了用户体验。
