图1为本公开实施例提供的对象的显示方法实施例的流程图,本实施例提供的该对象的显示方法可以由一对象的显示装置来执行,该对象的显示装置可以实现为软件,或者实现为软件和硬件的组合,该对象的显示装置可以集成设置在对象的显示系统中的某设备中,比如 对象的显示服务器或者对象的显示终端设备中。如图1所示,该方法包括如下步骤:
步骤S101,接收视频图像;
可选的,在该步骤中,所述接收视频图像为从图像传感器接收视频图像。所述图像传感器指可以采集图像的各种设备,典型的图像传感器为摄像机、摄像头、相机等。在该实施例中,所述图像传感器可以是终端设备上的摄像头,比如智能手机上的前置或者后置摄像头,摄像头采集的图像可以直接显示在手机的显示屏上,在该步骤中,接收图像传感器所拍摄的视频图像,作为对象的显示背景图像。
可选的,在该步骤中,所述接收视频图像为从存储器中接收视频图像文件,所述视频图像文件为事先录制完成的视频,并被保存在所述存储器中。可选的,所述存储器为本地存储器或者网络存储器。在该步骤中,接收从存储器中发送来的视频图像文件,并显示在设备的显示装置上作为对象的显示背景图像。
在该步骤中,所述视频图像中可以包括人脸,可选的,所述视频图像中的多个图像帧中至少有一帧中包括人脸。典型的,用户打开移动终端设备的摄像头对自己进行视频自拍,摄像头所获取到的视频图像中包括用户的人脸图像。或者所述视频图像文件中录制有人脸的图像。
步骤S102,识别所述视频图像中的目标对象;
其中所述目标对象可以是任何预先设置的需要从所述视频图像 中识别出来的对象,典型的目标对象可以是人脸。
识别视频图像中的目标对象可以使用任何目标识别算法。典型的如基于深度学习的,所述目标对象为人脸,则可以使用带有人脸的图像对神经网络进行训练,使用训练好的神经网络对所述视频图像中的每个图像帧进行分类以确定所述图像帧中是否包含人脸,当判断所述图像帧中包含人脸时,再使用人脸检测算法检测人脸的关键点以确定出人脸的位置;或者可以使用标记有人脸外接框的图像对神经网络进行训练,使用训练好的神经网络对所述视频图像中的每个图像帧进行外接框的回归以缩小人脸的范围,之后再使用人脸检测算法检测人脸的关键点以确定出人脸的位置;或者使用标记有人脸关键点的图像对神经网络进行训练,使用训练好的神经网络对所述视频图像中的每个图像帧进行人脸关键点回归以确定图像帧中是否包含人脸以及人脸关键点的位置。
可以理解的是,上述人脸以及识别方法仅仅是举例,不构成对本公开的限制,实际上可以根据要实现的效果以及场景预先选择目标对象以及针对所述目标对象的合适的识别算法。
步骤S103,响应于识别出第一目标对象,在所述视频图像的第一位置上显示具有第一形状的第一对象;
所述对象为虚拟的素材,用于显示在实际的视频图像中,典型的虚拟素材可以是贴图,所述贴图可以是静态的贴图也可以是序列帧贴图。
在该步骤中,当识别出所述视频图像中的第一目标对象,则获取 与所述第一目标对象对应的第一对象,并将所述第一对象现实与所述视频图像的第一位置上,其中所述第一对象具有第一形状。可选的,预先设置目标对象与对象的对应关系,当视频图像中出现目标对象时,从所述对应关系中获取与所述目标对象对应的对象,其中所述对应关系可以保存于配置文件中,通过配置文件可以配置要识别的目标对象、对象的类型、以及所述目标对象与对象的对应关系。
如图2所示,在该步骤中,所述响应于识别出第一目标对象,在所述视频图像的第一位置上显示所述第一对象,包括:
步骤S201,响应于识别出第一目标对象,获取所述第一目标对象的跟踪点;
步骤S202,根据所述第一目标对象的跟踪点计算所述第一位置;
步骤S203,在所述第一位置上显示所述第一对象。
在上述步骤中,当识别出第一目标对象,则第一目标对象的关键点也被检测出来,具体可以参见步骤S102中的描述。所述关键点中的一个或多个被预先设置为第一目标对象的跟踪点,或者根据所述关键点中的一个或多个确定所述跟踪点,所述跟踪点用于确定所述第一对象的显示位置。在步骤S202中,根据所述第一目标对象的跟踪点计算所述第一位置。可选的,所述第一目标对象为人脸。可选的,所述跟踪点为通过人脸鼻尖关键点和边缘关键点的连线的延长线上的点,位于人脸区域的外部,事先设定延长的比例,可以通过该比例计算从边缘点沿所述连线向外的长度以得到所述跟踪点。在步骤S203中,将第一对象的特定点与所述跟踪点重合,而将所述第一对象显示于所述第一位置上,可选的,所述第一对象的特定点为所述第一对象的中心点,将所述中心点的位置设置在所述跟踪点的位置上,以将所 述第一对象显示于所述第一位置上。由此,当第一目标对象在不同的图像帧的位置发生变化时,所述第一对象的位置也随之发生变化,达到第一对象跟随所述目标对象移动的效果。
可选的,所述响应于识别出第一目标对象,获取所述第一目标对象的跟踪点,包括:响应于识别出第一目标对象,判断所述第一目标对象在所述视频图像中的位置;根据所述第一目标对象在所述视频图像中的位置获取所述第一目标对象的跟踪点。在该实施例中,当识别出所述第一目标对象时,首先判断所述第一目标对象在所述视频图像中的位置,可选的,判断所述第一目标对象在所述视频图像的左边或者右边;根据所述第一目标对象的位置获取所述第一目标对象的跟踪点。可选的,所述第一目标对象为人脸,当判断所述第一目标对象位于所述视频图像的左边时,获取视频图像中人脸右侧的边缘关键点和人脸鼻尖关键点,以使所述跟踪点位于所述人脸的右侧(相对于观看视角);同样的,当判断所述第一目标对象位于所述视频图像的右边时,获取视频图像中人脸左侧的边缘关键点和人脸鼻尖关键点,以使所述跟踪点位于所述人脸的左侧。
在本公开中,所述第一对象具有第一形状。可选的,所述第一形状为一个完整形状的一部分,如第一形状可以为部分圆形、部分心形、部分矩形等等,第一形状也可以为一个完整的不规则形状的一部分,如部分的云、部分的山等等。
可以理解上,上述目标对象以及关键点的选择和跟踪点的计算均为举例,不构成对本公开的限制,实际上任何目标对象、关键点以及跟踪点的计算方法均可以应用到本公开的技术方案中。
步骤S104,响应于识别出第二目标对象,在所述视频图像的第 二位置上显示所述具有第二形状的第二对象;
可选的,所述响应于识别出第二目标对象,在所述视频图像的第二位置上显示所述第二对象,包括:响应于识别出第二目标对象,获取所述第二目标对象的跟踪点;根据所述第二目标对象的跟踪点计算所述第二位置;在所述第二位置上显示所述第二对象。
可选的,所述响应于识别出第二目标对象,获取所述第二目标对象的跟踪点,包括:响应于识别出第二目标对象,判断所述第二目标对象在所述视频图像中的位置;根据所述第二目标对象在所述视频图像中的位置获取所述第二目标对象的跟踪点。
可选的,所述第二形状与所述第一形状为互补形状。举例来说,所述第一形状为半个心形,则所述第二形状为另外半个心形。
上述可选步骤的具体实施方式可以与所述步骤S103中的第一目标对象和第一对象的可选步骤相同,在此不再赘述。
步骤S105,当所述第一目标对象和所述第二目标对象之间的距离小于第一阈值,将所述第一对象和第二对象进行结合以使所述第一对象和所述第二对象形成第三形状。
可选的,所述当所述第一目标对象和所述第二目标对象之间的距离小于第一阈值,包括:获取第一目标对象的第一锚点;获取第二目标对象的第二锚点;计算所述第一锚点和第二锚点之间的第一距离;当所述第一距离小于所述第一阈值,判断所述第一目标对象和所述第二目标对象之间的距离小于第一阈值。可选的,所述锚点可以是所述目标对象的关键点或者通过所述目标对象的关键点计算出的点,典型 的,所述锚点为人脸的鼻尖关键点,或者所述锚点为通过人脸上眼睛的关键点和鼻尖关键点所形成三角形的中点。当获取到锚点之后得到锚点的坐标,根据第一锚点的坐标和第二锚点的坐标计算出所述第一距离,所述第一距离表示所述第一目标对象和所述第二目标对象之间的距离,当第一距离小于预设的第一阈值时,所述第一目标对象和所述第二目标对象之间的距离之间的距离小于第一阈值。
可选的,所述第一对象和第二对象进行结合以使所述第一对象和所述第二对象形成第三形状,包括:将所述第一对象的第一形状和所述第二对象的第二形状按照互补的位置进行结合形成第三形状。典型的,所述第一形状和所述第二形状可以为互补的半个心形,当判断所述第一目标对象和第二目标对象的距离小于第一阈值,将两个互补的半个心形沿着它们互补的位置进行卯合以形成一个完整的心形。
通过上述步骤所描述的技术方案,可以通过计算图像中的两个目标对象之间的距离而使两个对象卯合在一起,无需预先录制视频并在视频中制作特效,其可以实时的渲染在任何视频图像中。
进一步的,如图3所示,在所述步骤S105之后,还包括:
步骤S301,当所述第一目标对象和所述第二目标对象之间的距离小于第二阈值,使第一对象和第二对象消失;
步骤S302,显示第一序列帧,所述第一序列帧中包括具有第三形状的第三对象。
在步骤S301中,可以根据步骤S105中的方法继续计算第一锚点 和第二锚点之间第一距离,当所述第一距离小于第二阈值时,判断所述第一目标对象和所述第二目标对象之间的距离小于第二阈值,此时控制所述第一对象和第二对象在所述视频图像中消失,所述消失可以是不再渲染所述第一对象和第二对象,也可以是将所述第一对象和第二对象的透明度设置为1使其透明不可见。
在步骤S302中,获取第一序列帧,并将所述第一序列帧显示于第一对象和第二对象消失的位置。所述第一序列帧中包括具有第三形状的第三对象,具体来说,所述第一序列帧中包括第三对象,且第一序列帧中的每一帧表示第三对象的状态变化,典型的,所述第三对象为一个虚拟的心,所述第一序列帧表示所述虚拟的心的动态变化,如从小变大从白色逐渐变化为红色等等。也即是说,所述第一序列帧表示所述第一对象和第二对象卯合之后所代表的第三对象的变化状态。
进一步的,如图4所示,在所述步骤S104之后,还可以包括:
步骤S401,计算所述第一目标对象和所述第二目标对象之间的距离;
步骤S402,根据所述距离获取所述第一对象和第二对象的变化参数;
步骤S403,根据所述变化参数改变所述第一对象和所述第二对象的显示状态。
在步骤S401中,同样可以使用步骤S105中所描述的方法计算第一目标对象和所述第二目标对象之间的距离,在此不再赘述。
在步骤S402中,获取变化参数,所述变化参数与所述距离相关,可以为预先设定的对应关系,如所述距离的第一值对应第一颜色值,第二值对应第二颜色值,由此可以通过所述距离控制所述对象的颜色变化等等。
在步骤S403中,根据所述变化参数改变所述第一对象和所述第二对象的显示状态。典型的,所述变化参数确定所述第一对象和所述第二对象的颜色,通过所述变化参数改变所述第一对象和所述第二对象的颜色。
上述步骤,通过两个目标对象之间的距离改变对象的显示状态。典型的,所述第一目标对象和所述第二目标对象为人脸,所述第一对象和所述第二对象分别为两个形状互补的半心形,当两个人脸靠近时,通过所述距离获取对应的对象颜色,如从浅红色到深红色,距离越近颜色越深,这样颜色与人脸之间的距离对应,可以实时对图像进行渲染而无需后期对每帧图像中的对象分别制作不同的形态。
本公开公开了一种对象的显示方法、装置、电子设备和计算机可读存储介质。其中该对象的显示方法包括:接收视频图像,所述视频图像包括多个图像帧;识别所述视频图像的图像帧中的目标对象;响应于识别出第一目标对象,在所述视频图像的第一位置上显示具有第一形状的第一对象;响应于识别出第二目标对象,在所述视频图像的第二位置上显示所述具有第二形状的第二对象;当所述第一目标对象和所述第二目标对象之间的距离小于第一阈值,将所述第一对象和第 二对象进行结合以使所述第一对象和所述第二对象形成第三形状。通过上述方法,解决了现有技术中无法简单快速的生成视频效果的技术问题。
