为了使本技术领域的人员更好地理解本申请方案,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象,而不是用于描述特定顺序。此外,术语“包括”和“具有”以及它们任何变形,意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元,而是可选地还包括没有列出的步骤或单元,或可选地还包括对于这些过程、方法、产品或设备固有的其他步骤或单元。
在本文中提及“实施例”意味着,结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例,也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是,本文所描述的实施例可以与其它实施例相结合。
本申请实施例所涉及到的电子设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备(user equipment,UE),移动台(mobile station,MS),终端设备(terminal device)等等。为方便描述,上面提到的设备统称为电子设备。下面对本申请实施例进行详细介绍。
可选地,本申请实施例中的电子设备可安装有人工智能模块(artificial intelligence,AI),该人工智能模块可单独于处理器安装在电子设备中,例如,处理器调用AI模块实现人工智能,当然,也可以与处理器集成在一起,这时候,处理器就相当于AI模块。该人工智能模块可为量子芯片,或者,高密度硅集成电路,AI模块中可存储有机器学习算法,用于对用户使用习惯(例如,收集用户的喜好,喜好的图像)进行训练,以及对用户使用习惯进行深度学习,从而,通过AI模块达到对电子设备进行智能化控制的目的。
请参阅图1,为本申请实施例提供的一种图像处理方法的实施例流程示意图。本实施例中所描述的图像处理方法,包括以下步骤:
101、获取目标图像集,所述目标图像集中包含N张图像,所述N为大于1的整数。
其中,目标图像集中可包含以下图像中的至少一种:用于收藏的图像、用于发朋友圈的图像、用于发送给社交好友的图像、用户多次查看的图像(查看次数大于预设查看次数的图像,预设查看次数可由系统默认或者用户自行设置)等等。目标图像集中可包含N张图像,N为大于1的整数。
可选地,上述步骤101中,获取目标图像集,可包括如下步骤:
A1)、对相册中的每一图像的控制指令进行监控;
A2)、将所述相册中符合预设条件的控制指令对应的图像组成所述目标图像集。
其中,上述控制指令可为以下至少一种:查看指令,发送指令,收藏指令,删除指令,P图指令(对图像进行PS(PhotoShop)处理)等等。因而,可对相册中的每一图像进行监控,例如,用户查看某一图像时,则可监控到对该图像的查看指令,又例如,用户收藏某一图像时,则可监控到对该图像的收藏指令,又例如,用户转发某一图像时,则可监控到对该图像的发送指令。预设条 件可由用户自行设置或者系统默认。例如,预设条件可为控制指令为收藏指令,又例如,预设条件可为控制指令为发送指令。通常情况下,电子设备都有相册,可将相册中符合预设条件的控制指令对应的图像组成目标图像集,如此,可通过用户对照片的操作,分辨出用户喜好的图像。例如,有的用户喜欢鲜艳,则其对鲜艳类型的图像实施收藏或者发朋友圈的概率较大,又例如,有的用户喜欢淡雅,则其对淡雅类型的图像实施收藏或者发朋友圈的概率较大。另外,很多时候,用户不用关心对图像的处理方式,但是,通过对图像的偏好,可得到用户喜欢的色温、白平衡的处理效果。如此,可在一定程度上,折射出用户对图像的喜好。
可选地,上述步骤101中,获取目标图像集,可包括如下步骤:
B1)、对相册中的M张图像中的每一图像进行图像质量评价,得到所述M个图像质量评价值,所述M为大于1的整数;
B2)、从所述M个图像质量评价值中选取大于预设图像质量阈值的图像质量评价值,得到所述N个图像质量评价值,并获取其对应的图像,得到所述目标图像集。
其中,上述M张图像可为预设时间段的所有图像,或者,为电子设备中存储的所有图像。上述预设时间段可由用户自行设置或者系统默认,之所以设置预设时间段,考虑到随着时间的推移,用户的喜好也会改变,例如,现在的喜好,与几年前的喜好会存在一定的差异,为了迎合用户喜好的改变,可预先设置一个预设时间段。上述预设图像质量阈值可由用户自行设置或者系统默认。因而,可对相册中的M张图像中的每一图像进行图像质量评价,得到M个图像质量评价值,M为大于或等于N的整数,再者,从M个图像质量评价值中选取大于预设图像质量阈值的图像质量评价值,得到N个图像质量评价值,并获取其对应的图像,得到所述目标图像集。
进一步地,上述步骤B1中,对相册中的M张图像中的每一图像进行图像质量评价,可采用下述方式:
采用至少一个图像质量评价指标对相册中的M张图像中的每一图像进行图像质量评价。
其中,上述图像质量评价指标可包括但不仅限于:平均灰度、均方差、熵、边缘保持度、信噪比等等,在采用多个图像质量评价值对某一图像进行图像质 量评价时,每一图像质量评价指标也对应一个权重,如此,每一图像质量评价指标对照片进行图像质量评价时,均可得到一个评价结果,最终,进行加权运算,也就得到最终的图像质量评价值。
需要说明的是,由于采用单一评价指标对图像质量进行评价时,具有一定的局限性,因此,可采用多个图像质量评价指标对图像质量进行评价,当然,对图像质量进行评价时,并非图像质量评价指标越多越好,因为图像质量评价指标越多,图像质量评价过程的计算复杂度越高,也不见得图像质量评价效果越好,因此,在对图像质量评价要求较高的情况下,可采用2~10个图像质量评价指标对图像质量进行评价。具体地,选取图像质量评价指标的个数及哪个指标,依据具体实现情况而定。当然,也得结合具体地场景选取图像质量评价指标,在暗环境下进行图像质量评价和亮环境下进行图像质量评价选取的图像质量指标可不一样。
可选地,在对图像质量评价精度要求不高的情况下,可用一个图像质量评价指标进行评价,例如,以熵对待处理图像进行图像质量评价值,可认为熵越大,则说明图像质量越好,相反地,熵越小,则说明图像质量越差。
可选地,在对图像质量评价精度要求较高的情况下,可以采用多个图像质量评价指标对图像进行评价,在多个图像质量评价指标对图像进行图像质量评价时,可设置该多个图像质量评价指标中每一图像质量评价指标的权重,可得到多个图像质量评价值,根据该多个图像质量评价值及其对应的权重可得到最终的图像质量评价值,例如,三个图像质量评价指标分别为:A指标、B指标和C指标,A的权重为a1,B的权重为a2,C的权重为a3,采用A、B和C对某一图像进行图像质量评价时,A对应的图像质量评价值为b1,B对应的图像质量评价值为b2,C对应的图像质量评价值为b3,那么,最后的图像质量评价值=a1b1+a2b2+a3b3。通常情况下,图像质量评价值越大,说明图像质量越好。
102、获取所述N张图像中每一图像对应的拍摄参数,得到所述N组拍摄参数集,每一拍摄参数集对应多个拍摄参数。
其中,N张图像中每一图像对应多个拍摄参数,该多个拍摄参数可理解为一个拍摄参数集,于是,N张图像可得到N组拍摄参数集。
可选地,拍摄参数为拍照时候,调节摄像头或者处理拍照图像的参数或者 环境参数,拍摄参数可包括但不仅限于:感光度ISO值、曝光时长、焦距、白平衡参数、光通量、环境亮度、天气、海拔、地理位置、防抖参数等等。当然,每一图像对应的拍摄参数个数也可以不一样,例如,有的时候拍照需要闪光灯,有的时候拍照不需要闪光灯。其中,曝光时长为:从快门打开到关闭的时间间隔,在这一段时间内,物体可以在底片上留下影像。感光度ISO值是用数字表示对光线的敏感度,ISO感光度越高,表示对光线的敏感度越强。高ISO感光度适合拍摄低光照及运动物体,但是图像可能包含噪点并且显得颗粒感增大,低ISO感光度虽然不适合拍摄低光照及运动物体,但图像更细腻。光通量是指按照国际规定的标准人眼视觉特性评价的辐射通量的导出量,具体地,光通量(luminous flux)指人眼所能感觉到的辐射功率,它等于单位时间内某一波段的辐射能量和该波段的相对视见率的乘积,由于人眼对不同波长光的相对视见率不同,所以不同波长光的辐射功率相等时,其光通量并不相等,当然,在亮光环境情况下,光通量较小,在弱光环境下,光通量较大。白平衡参数用来调节白平衡效果的参数。
103、对所述N组拍摄参数集进行合成,得到M个目标拍摄参数集,所述M为小于所述N的正整数。
其中,N组拍摄参数集分别针对N张不同的图像而言,因而,可对N组拍摄参数集进行合成处理,其目的在于,得到可针对某一类图像的拍摄参数集,即,每一拍摄参数集对应一个场景,得到M个目标拍摄参数集,M为小于或等于N的正整数。
可选地,上述步骤103中,对所述N组拍摄参数集进行合成,得到M个目标拍摄参数集,包括:
31)、获取所述N组拍摄参数集中每一组拍摄参数集对应的环境亮度,得到所述N个环境亮度值;
32)、将所述N个环境亮度值进行亮度等级划分,并获取每一亮度等级对应的拍摄参数集,得到所述M个集合;
33)、对所述M个集合中每一集合对应的拍摄参数集进行合成,得到所述M个目标拍摄参数集。
其中,可获取N组拍摄参数集中每一组拍摄参数集对应的环境亮度,可得到N个环境亮度值,可对该N个环境亮度值进行亮度等级划分,并获取每 一亮度等级对应的拍摄参数集,于是得到M个集合,对M个集合中的每一集合对应的拍摄参数集进行合成,可得到M个目标拍摄参数集。如此,可得到每一亮度等级对应的拍摄参数集,于是,在检测到环境亮度处于某个亮度等级,则可调用相应的拍摄参数集进行拍摄。
可选地,上述步骤33,对所述M个集合中每一集合对应的拍摄参数集进行合成,得到所述M个目标拍摄参数集,可按照如下方式执行:
对集合i中K组拍摄参数集中每一拍摄参数进行线性拟合,得到多个拟合拍摄参数,将其组成所述集合i为对应的目标拍摄参数集,所述集合i为所述M个集合中的任一个,所述K为正整数。
其中,对于M个集合中的每一集合而言,其包含多组拍摄参数集,每一拍摄参数集包含多个拍摄参数,于是,可对每一集合中的多组拍摄参数集进行线性拟合,得到多个拟合拍摄参数,该多个拟合拍摄参数则构成该每一集合对应的目标拍摄参数集。
可以看出,上述本申请实施例中,获取目标图像集,目标图像集中包含N张图像,N为大于1的整数,获取N张图像中每一图像对应的拍摄参数,得到N组拍摄参数集,每一拍摄参数集对应多个拍摄参数,对N组拍摄参数集进行合成,得到M个目标拍摄参数集,M为小于N的正整数,从而,可根据用户对图像的使用情况或者图像质量评价,得到认为好的图像,并对这些图像对应的拍摄参数进行合成,得到针对具体场景的拍摄参数,如此,可以自适应获取拍摄参数,容易拍出用户喜好的图像。

其中,上述步骤201-步骤203可参照图1所描述的图像处理方法的相应步 骤,在此不再赘述。
204、在接收到拍照指令时,获取当前环境参数。
其中,当前环境参数可包括但不仅限于:环境亮度、天气、地理位置等等,在接收到拍照指令之后,可获取当前环境参数。例如,环境亮度可由电子设备自带的环境光传感器检测到,天气可由电子设备的天气应用获取,地理位置可由电子设备进行定位得到。
205、根据所述当前环境参数从所述M个目标拍摄参数集中选取一组目标拍摄参数集,并根据该目标拍照参数集进行拍照。
其中,不同的环境参数对应不同的目标拍摄参数集,可根据当前环境参数获取与之对应的目标拍摄参数集,并根据该目标拍摄参数集进行拍照。
