如图1所示,一种图像标记数据处理还原系统,可以改善诸如本地和远程等不同数据端的数据传输延时问题,包括第一数据端和第二数据端,所述第一数据端采集图像数据;所述第一数据端将所述图像数据传输至所述第二数据端,记为第一图像数据,所述第一数据端同时将所述图像数据备份,记为第二图像数据;所述第二数据端接收并输出所述第一图像数据,并从所述第一图像数据中选取一帧第一图像,在所述第一图像上叠加一张大小与所述第一图像大小一致的第一灰度图像;所述第二数据端在所述第一灰度图像上实现信息标记,然后将信息标记后的所述第一灰度图像坍缩成带有时间戳信息的二进制数据,在所述二进制数据上添加一个时间戳信息,所述时间戳信息与所述第一图像在所述第一图像数据中的时间顺序对应,并将所述二进制数据回传至所述第一数据端;所述第一数据端接收所述带有时间戳信息的二进制数据,并根据所述二进制数据上的时间戳信息从第二图像数据中找到对应的一帧第二图像,创建一张大小与所述第二图像大小一致的第二灰度图像,根据所述二进制数据在所述第二灰度图像上实现信息标记还原,最后将带有信息标记的第二灰度图像与所述第二图像实现叠加输出。
将上述所述的图像标记数据处理还原系统应用在远程医疗图像标记传输中加以说明:
步骤1:本地端(即第一数据端)通过影像设备(如Camera)采集病人病灶信息,得到源影像。其中,影像设备也可以是内窥镜设备,只要能获取图像即可。
其中,采集的图像数据可以是若干张连续或不连续的图片,也可以是一段视频图像。
步骤2:本地端将获取的源影像分两路输出:一路把源影像压缩后形成第一图像数据,通过网络传输到远程端(即第二数据端);另外一路把源影像备份形成第二图像数据,以便后面的合成。
其中,所述对源影像的压缩可以根据需要通过不同的压缩算法实现,如h264(H264一般指H.264。H.264,同时也是MPEG-4第十部分,是由ITU-T视频编码专家组(VCEG)和ISO/IEC动态图像专家组(MPEG)联合组成的联合视频组(JVT,Joint Video Team)提出的高度压缩数字视频编解码器标准),或者h265(H.265是ITU-T VCEG继H.264之后所制定的新的视频编码标准)等压缩算法。
其中,可以通过如5G网络传输将压缩后形成的第一图像数据传输到远程端。
步骤3:远程端通过网络接收到第一图像数据后,采用步骤2的压缩算法的反向算法对第一图像数据进行解码,并将解压后的第一图像数据显示在显示器上供专家诊断。
步骤4:专家通过观看第一图像数据,在第一图像数据中选取一帧合适的第一图像(所述合适的一帧图像是指能较好地显示病灶的信息的图像),在第一图像上叠加一张与第一图像同样大小的第一灰度蒙版(即第一灰度图像(用灰度表示的图像称作灰度图),只有一个通道),并将第一灰度蒙版的像素值全部初始化为0,该灰度图叠加在第一图像上时,可以达到蒙版透明的效果(即只在第一图像上显示标记信息,而不显示第一灰度蒙版,好像第一灰度蒙版是透明的一样)。
步骤5:专家通过诸如触摸设备(如电子笔)在第一灰度蒙版与第一图像对应的位置上勾选出有病变的组织和/或添加文字等诊断信息。此时专家的诊断笔迹是留在第一灰度蒙版上的。
步骤6:远程端把带有时间戳信息和诊断信息的第一灰度蒙版,坍缩成二进制的诊断数据(即二进制数据),并在数据内加入时间戳信息,所述时间戳信息与所述第一图像数据中的时间顺序对应。
具体办法如下:把第一灰度蒙版的每个8位像素值(即8位灰度图像:每个像素存放在一个byte空间)对应成诊断数据中的1个bit位,即把第一灰度蒙版的每个像素值中非零的数值转换为1,把第一灰度蒙版的每个像素值中为零的数值转换为0,将数据转换后的第一灰度蒙版转换成二进制诊断数据,这样坍缩后的诊断数据的大小就会变为第一灰度蒙版的1/8,最后在数据的头部信息里加入一个32位的时间戳,时间戳与所述第一图像在所述第 一图像数据中的时间顺序对应(这里的对应可以理解为时间顺序一致或者通过某个算法找出两者之间的关系)。
因为在本地端接收诊断数据后,会创建一张第二灰度图像,根据所述二进制数据在所述第二灰度图像上实现信息标记还原,最后将带有信息标记的第二灰度图像与所述第二图像实现叠加输出。而在将第二灰度图像与第二图像数据的图像进行叠加时,主要是要显示远程端专家的标记信息(而不要求标记信息的亮度变化),所以,把第一灰度蒙版的每个像素值中非零的数值转换为二进制1,把第一灰度蒙版的每个像素值中为零的数值转换为二进制0形成二进制数据流,这样在本地端接收二进制数据流后把二进制流的数据段每个位膨胀成8位灰度图像形成第二灰度图像(所述第二灰度图像中,有标记信息的地方的像素值为255,没有标记信息的地方的像素值为0)。这样,远程端在回传专家标记信息时,不需要回传大量的图像数据,而只需要传输带有时间戳信息和诊断信息的二进制数据,从根本上解决了数据网络传输延时的问题。
步骤7:远程端把诊断数据进一步压缩(这里的压缩采用一般的压缩方法即可)后通过网络传递给手术本地端。
步骤8:本地端收到远程端的诊断数据后,采用步骤7的反压缩技术,解压出诊断数据。
步骤9:本地端通过诊断数据上的时间戳信息从第二图像数据中找到对应的一帧第二图像,本地端通过膨胀把二进制的诊断数据转变为带有专家诊断信息的蒙版(即第二灰度图像)。
其中,膨胀方法与步骤6相反,具体过程如下:通过诊断数据头上的时间戳信息从第二图像数据中找到对应的一帧第二图像,创建一张大小与所述第二图像大小一致的第二灰度图像,并将第二灰度图像的像素值全部初始化蒙版值为0,将第二灰度图像与诊断数据按像素逐一对比,将第二灰度图像中与诊断数据为1对应的像素设置为255,将第二灰度图像中与诊断数据为0对应的像素设置为0,如此得到像素值与诊断数据对应的第二灰度图像。步骤10:把第二灰度图像与第二图像进行叠加,即可还原出专家在源影像中标记的位置。
如图2所示,本技术方案还保护一种低传输量的图像标记数据处理方法,具体包括以下步骤:
A1:接收并输出第一图像数据。
其中,所述第一图像数据由其他数据端传输过来。当所述第一图像数据为压缩数据时,还需要对所述第一图像数据进行解压后输出。
A2:从所述第一图像数据中选取一帧第一图像。
A3:在所述第一图像上叠加一张大小与所述第一图像大小一致的第一灰度图像。
其中,大小与所述第一图像大小一致的第一灰度图像,是指第一灰度图像上的像素点的数量且位置与所述第一图像上的像素点的数量和位置一一对应。
在某些实施例中,所述第一灰度图像通过以下过程处理得到:在所述第一图像上创建一张大小与所述第一图像一致的灰度图像,将灰度图像的像素值全部初始化为0,得到第一灰度图像。
A4:在所述第一灰度图像上实现信息标记。
其中,可以通过诸如触摸设备(如电子笔)在第一灰度图像与第一图像对应的位置上勾选出有病变的组织和/或添加文字等诊断信息。此时专家的诊断笔迹是留在第一灰度图像上的。
A5:将信息标记后的所述第一灰度图像坍缩成带有时间戳信息的二进制数据,在所述二进制数据上添加一个时间戳信息,所述时间戳信息与所述第一图像在所述第一图像数据中的时间顺序对应。
其中,所述A5中,具体过程如下:如图3所示,把第一灰度图像上的每个像素值(每个像素值包括8位灰度图像值)对应成二进制数据中的1个bit位,即把第一灰度图像的每个像素值中非零的数值(每个像素值包括8位灰度图像值)转换为1,把第一灰度图像的每个像素值中为零的数值转换为0,将数据转换后的第一灰度图像转换成二进制数据。
进一步地,还可以对坍缩后的有时间戳信息的二进制数据采用压缩方法进行压缩,进一步减少数据传输量。其中,所述压缩方法可以根据需要通过不同的压缩算法实现(这里的压缩算法采用一般的数据压缩方法即可)。
A6:将所述带有时间戳信息的二进制数据输出。

其中,大小与所述第二图像大小一致的第二灰度图像,是指第二灰度图像上的像素点的数量且位置与所述第二图像上的像素点的数量和位置一一对应。
在某些实施例中,所述第二灰度图像通过以下过程处理得到:在所述第二图像上创建一张大小与所述第二图像一致的灰度图像,将灰度图像的像素值全部初始化为0,得到第二灰度图像。
其中,根据所述二进制数据在所述第二灰度图像上实现信息标记还原,具体过程如下:如图6所示,将所述二进制数据还原成8位灰度图像值,将所述第二灰度图像与所述8位灰度图像值按像素逐一对比,将与所述8位灰度图像值中为1的位置对应的所述第二灰度图像每个像素中的对应数值设置为255,将与所述8位灰度图像值中为0的位置对应的所述第二灰度图像每个像素中的对应数值设置为0,在第二灰度图像上实现信息标记还原。
B4:将带有信息标记的第二灰度图像与所述第二图像实现叠加并输出。
其中,可以一边播放备份的第二图像数据,然后在显示窗口叠加一个对比显示窗口播放叠加后的第二灰度图像与第二图像,与备份的第二图像数据进行对比。除非有新的叠加后的第二灰度图像与第二图像,会将前一张图像替换掉,否则该对比显示窗口会一直显示叠加后的第二灰度图像与第二图像,直到设备关闭,或人为将按键将该对比显示窗口关闭。
