Description
本发明涉及图像处理领域,尤其涉及一种图像重构方法、装置、电子设备和存储介质。
近20年来,随着衍射极限的突破,技术以及荧光探针的发展,超分辨显微技术已经成为观察研究生物细胞活动的重要方法。它从原理上大致可分为三种:第一种是利用荧光物质开关效应的单分子定位成像方法,例如光激活定位显微术(Photoactivated Localization Microscopy,PALM)和随机光学重构显微术(Stochastic Optical Reconstruction Microscopy,STORM)。样品被荧光探针标记后,用一束激活光激活荧光分子,另一波长激发光激发荧光分子并成像。但这两种技术都需要采集很多幅原始图像,时间分辨率低;第二种是基于荧光非线性效应,对点扩散函数进行减小的显微术。典型技术代表为受激发射损耗显微术(Stimulated Emission Depletion,STED)。一束激光激发荧光分子,一束环形损耗光来将激发光斑焦点外围的荧光擦除,从而限制发生受激辐射的地方,减小点扩散函数,提高分辨率。STED采用点扫描,不利于大面积的成像,时间分辨率低。而且需要用功率较高的损耗光才能实现高的空间分辨率,但这样会造成光漂白和细胞损伤;第三种是结构光照明显微术(Structured Illumination Microscopy,SIM)。用周期性的结构光照射被荧光标记的样品,被测样品的空间频率和照明图案的空间频率不同的地方会产生莫尔条纹,根据已知的照明图案的频率可解出被测样品的空间频率。这种显微术属于宽场成像,但也需要采集多帧图像,时间分辨率低。总体上讲,这几种典型的超分辨显微 技术都存在一个共同的缺点:成像速度慢,时间分辨率都比较低,不利于实现对细胞信息的动态观察。

现有技术中的超分辨显微技术存在成像速度慢,时间分辨率较低的缺点,不利于实现对细胞信息的动态观察,为了解决现有技术中的问题,本发明实施例提出一种图像重构方法,参见图1,该图像重构方法包括:
步骤101、获取显微镜系统采集的目标样本的单帧的宽场图像I
0;
本实施例中显微镜系统包括显微镜以及和该显微镜结合来获取显微镜成像图像的相机。本实施例中,相机可以是CCD相机或CMOS相机,本实施例对此没有限制。
本实施例的图像重构方法可以是由终端实现,该终端包括但不限于如手机等移动终端以及如电脑等固定终端。步骤101中获取显微镜系统采集的目标样本的单帧的宽场图像I
0包括:接收显微镜系统中相机发送的目标样本的单帧的宽场图像I
0。
步骤102、设置与宽场图像I
0的尺寸相同的数字模板P
i,其中i=1…N;
步骤103、根据公式I
i=I
0*P
i,计算数字模板P
i对应的光强分布I
i,其中,* 表示点乘;
本实施例中,宽场图像I
0的尺寸和N个数字模板P
i的尺寸相同,即宽场图像I
0的矩阵和数字模板P
i的矩阵具有相同的行数和列数。数字模板P
i与宽场图像I
0点乘,实际上就是P
i的矩阵和I
0的矩阵中的相同位置的元素相乘。
将
代入公式I
i=I
0*P
i,并进行展开可以得到I
i(x,y)=[∫∫S(u,v)H(x-u,y-v)dudv]P
i(x,y),其中,(x,y)表示显微镜系统中拍摄宽场图像I
0的相机的成像平面上的坐标(相机的成像平面上建立的是xy坐标系);(u,v)表示目标样本所在平面上的坐标(目标样本所在平面上建立的是uv坐标系)。
步骤104、根据公式T
i=∫I
i,计算光强分布I
i的积分T
i;
具体的,根据已知的I
0和P
i,计算与数字模板P
i对应的光强分布I
i的积分T
i。另一方面,将I
i(x,y)=[∫∫S(u,v)H(x-u,y-v)dudv]P
i(x,y)代入T
i=∫I
i,得到积分T
i的表达式为:
T
i=∫I
i=∫∫(∫∫S(u,v)H(x-u,y-v)dudv)P
i(x,y)dxdy
对式子T
i=∫I
i=∫∫(∫∫S(u,v)H(x-u,y-v)dudv)P
i(x,y)dxdy进行变形可以得到:
T
i=∫∫(∫∫S(u,v)H(x-u,y-v)dudv)P
i(x,y)dxdy=∫∫S(u,v)dudv(∫∫P
i(x,y)H(x-u,y-v)dxdy)
∫∫S(u,v)dudv(∫∫P
i(x,y)H(x-u,y-v)dxdy)
所以I
i的积分结果和I′
i的积分结果相等。依据I
i和I′
i的积分值相等的结论,当我们得到原始的宽场图像I
0与数字模板P
i点乘结果的积分值时,同样可以认为该积分值是对光强分布I′
i积分得到。
所以,
在这个式子中,积分T
i在步骤104中已计算得到,P
i在步骤102中已获取,所以只要获取点扩散函数H,在
中就只有S为未知,其它均为已知,根据已知的积分T
i、数字模板P
i和点扩散函数H求解S即可。T
i
步骤105、获取显微镜系统的点扩散函数H;
具体的,当我们测量显微镜系统的点扩散函数H之后,将点扩散函数H分别与i=1······N的N个数字模板P
i进行卷积,可以得到模糊数字模板P′
i,其中
将模糊数字模板P′
i视为新的数字模板时,新的光强分布I′
i可以看做为:
I′
i=P′
i*S
同时,
T
i=∫I′
i=∫P′
i*S
在式子T
i=∫I′
i=∫P′
i*S中,数字模板P′
i与光强分布I′
i的积分值T
i是已知的,这种情况与单像素相机成像原理相同。基于积分T

i时,同样可以获得大量的模糊数字模板P′
i以及对应光强分布积分值T
i。

集成的模块如果以软件功能模块的形式实现并作为独立的产品销售或使用时,可以存储在一个计算机可读取存储介质中。基于这样的理解,本发明的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的全部或部分可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质中,包括若干指令用以使得一台计算机设备(可以是个人计算机,服务器,或者网络设备等)执行本发明各个实施例方法的全部或部分步骤。而前述的存储介质包括:U盘、移动硬盘、只读存储器(ROM,Read-Only Memory)、随机存取存储器(RAM,Random Access Memory)、磁碟或者光盘等各种可以存储程序代码的介质。
需要说明的是,对于前述的各方法实施例,为了简便描述,故将其都表述为一系列的动作组合,但是本领域技术人员应该知悉,本发明并不受所描述的动作顺序的限制,因为依据本发明,某些步骤可以采用其它顺序或者同时进行。其次,本领域技术人员也应该知悉,说明书中所描述的实施例均属于优选实施例,所涉及的动作和模块并不一定都是本发明所必须的。
在上述实施例中,对各个实施例的描述都各有侧重,某个实施例中没有详述的部分,可以参见其它实施例的相关描述。
以上为对本发明所提供的一种图像重构方法、装置、电子设备和存储介质的描述,对于本领域的技术人员,依据本发明实施例的思想,在具体实施方式及应用范围上均会有改变之处,综上,本说明书内容不应理解为对本发明的限 制。
