具体实施方式
下文中将结合附图对本公开的实施例进行详细说明。在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以 以不同于此处的顺序执行所示出或描述的步骤。
本公开实施例中，在系统壁纸变化时完成壁纸特征信息的提取，并通过对特征信息的比对与确认过程，完成壁纸关联状态的设置与同步过程。
如图1所示，本公开实施例的壁纸管理的方法，包括如下步骤：
步骤110，确定待切换壁纸。
其中，可以通过监听壁纸的切换信息，根据所述切换信息确定待切换壁纸。例如监听系统广播，获取切换信息，所述切换信息可以包括待切换壁纸的标识。所述待切换壁纸是指选定的切换后的壁纸，即需要将当前壁纸切换为待切换壁纸。
步骤120，获取待切换壁纸的特征信息，将所述待切换壁纸的特征信息与特征数据库中壁纸的特征信息进行比对，确定所述特征数据库中与所述待切换壁纸匹配的壁纸。
所述特征数据库保存有壁纸资源中壁纸的特征信息，还可以保存有壁纸的分类属性信息和内容信息。
其中，所述特征信息可以包括特征主键，还可以包括特征辅助键。特征数据库中壁纸的特征信息还可以包含有特征附加键和自定义特征键。
其中，特征主键指用于识别壁纸的主要特征属性，具有唯一性。在本公开实施例中，可以通过对壁纸处理，进行灰度特征值分析得到该特征主键。
特征辅助键指用于识别壁纸的辅助特征属性，不唯一，辅助特征主键进行壁纸识别。在本公开实施例中，特征辅助键可以包括壁纸的主色调。
特征附加键用于壁纸生效后视效展示，可以包括前景文字颜色和状态栏颜色中的至少之一。
自定义特征键是预先有视效设计的，与壁纸关联的特征属性，主要来源于预先设定的配置文件。
步骤130，按照所述匹配的壁纸对应的特征信息进行壁纸切换。
在本公开实施例中，通过进行特征信息匹配，避免了由于应用内部的重重传递与外部设置壁纸接口引起异常，导致应用中记录的壁纸状态与系统中被设 置的壁纸状态不一致的情况。
如图2所示，在一实施例中，步骤110之前，所述方法还包括：
步骤200，获取壁纸资源中壁纸的特征信息，存入特征数据库中。
同样的，所述特征信息可以包括特征主键，还可以包括特征辅助键、特征附加键以及自定义特征键。
特征主键和特征辅助键用于步骤120中的壁纸比对，特征附加键和自定义特征键用于步骤130切换后壁纸的展示。
在步骤200中，可以将系统中预置的壁纸资源与用户下载的线上壁纸资源的特征信息初始化到特征数据库中。另外，还可以将辅助的自定义信息(即自定义特征键)保存到特征数据库。
在步骤200中，首先获取系统中可以被设置为壁纸的资源。所述壁纸资源可以包括如下至少之一：移动终端预置的壁纸、桌面自定义壁纸资源包、下载的壁纸资源、下载的主题中的壁纸资源、动态壁纸资源包。其中，移动终端预置的壁纸可以是移动终端系统层预置的壁纸，下载的壁纸资源和下载的主题中的壁纸资源可以是用户从线上美化商店下载的。不同类型的资源，由于是存储方式的差异，获取方式可能有所不同，可采样已有的获取方式实现，此处不再赘述。
在一实施例中，如图3所示，所述获取壁纸资源中壁纸的特征信息，包括：
步骤301，将所述壁纸的尺寸缩放成目标壁纸尺寸。
其中，由于壁纸资源中壁纸的尺寸不一，另外壁纸资源中壁纸的尺寸通常较大，计算处理较复杂，故本步骤中，将其缩放为合适的尺寸。这个过程也可称为格式化。
步骤302，确定缩放后壁纸的特征主键。
其中，将缩放后壁纸划分为多个区块，进而计算每个区块对应的特征值，得到特征主键。
在步骤301之前，还可以对所述壁纸资源中的壁纸进行排序。
其中，可以按照需求指定的序列进行排序。例如，针对桌面自定义壁纸资 源包，在桌面启动时第一时间加载与计算；线上美化商店下载的壁纸资源与推荐壁纸相关。
如图4所示，在一实施例中，所述目标壁纸尺寸包括目标壁纸宽度，所述将所述壁纸的尺寸缩放成目标壁纸尺寸，包括：
步骤401，根据所述目标壁纸宽度确定缩放比。
其中，目标壁纸宽度为W T arg et，根据W T arg et和壁纸资源中壁纸的宽度W Res生成缩放比。
R＝W Res/W T arg et
步骤402，按照所述缩放比对所述壁纸进行缩放。
其中，如果缩放比R小于2，则可以设置缩放比R＝1。
如图5所示，在一实施例中，在步骤402之后，还可以包括：
步骤501，检查缩放后的壁纸，判断壁纸的宽度是否大于W T arg et。如果处理后的壁纸的宽度仍大于W T arg et，则再一次执行步骤401～402对壁纸进行缩放，使之小于等于W T arg et，以保证提取壁纸特征时的精度。如果壁纸的宽度小于等于W T arg et，则继续执行步骤302。
本公开实施例中的缩放为等比例缩放，调整宽度时，同时也调整了高度。
另外，目标壁纸尺寸也可以包括目标壁纸高度，也可以按照目标壁纸高度对壁纸进行缩放。
如图6所示，在一实施例中，所述根据所述目标壁纸宽度确定缩放比之前，所述方法还包括：
步骤600，根据宽度预设值和移动终端宽度确定所述目标壁纸宽度。
目标壁纸宽度可以是预设值，也可以根据宽度预设值和移动终端宽度确定。例如，目标壁纸宽度可以设置为：
W T arg et＝Math.max(W m,W phone/12)
其中，W m为宽度预设值，超过这个宽度，壁纸的特征计算时间将过长，影响用户设置壁纸的流程。这个值为经验值，在大量计算后，考虑手机计算能力与壁纸的一般尺寸后确定。W phone为移动终端的宽度。
如图7所示，在一实施例中，所述确定缩放后壁纸的特征主键包括：
步骤701，将所述缩放后壁纸划分为多个区块；
其中，采用一个固定的比例进行划分。记每个区块的宽度为W Scale，高度为H Scale。
缩放后壁纸划分为R1×R2个，其中，
其中，R1＝W T arg et/W Scale、R2＝H T arg et/H Scale
步骤702，确定每个区块的灰度特征值；
其中，如图8所示，在一实施例中，所述步骤702，包括：
步骤801，确定每个区块中的红、绿和蓝三种颜色的颜色特征值的均值；
其中，红、绿和蓝三种颜色的颜色特征值分别为：R B、G B、B B,其中
R B＝∑Color.red(P)
其中，P为区块中像素点，∑Color.red(P)表示对区块中每个像素点的红色值累加和。同理可得，G B与B B。
每个区块中的红、绿和蓝三种颜色的颜色特征值的均值为R B、G B、B B分别除以像素的个数，将三个颜色的均值记录在数组A R1*R2中。
步骤802，将每个区块中红、绿和蓝三种颜色的颜色特征值的均值进行灰度化处理，得到每个区块的灰度特征值。
其中，按照下式将A R1*R2中的特征值灰度化，处理后的数据保存在G R1*R2中
V＝0.3r+0.58g+0.12b
其中，r,g,b分别表示A R1*R2中红、绿、蓝三种颜色值。
步骤703，确定所述多个区块的灰度特征值的均值；
其中，对每个区块的灰度特征值进行平均，也即对G R1*R2中的值进行平均，得到均值A g。
步骤704，将所述均值与每个区块的灰度特征值进行比较，确定所述特征主键。
其中，比较G R1*R2与A g的关系，若数据中的值大于A g，则特征值为1，否则 为0。这样便可以生成一个包含R1×R2个特征单元的字符串，作为所述特征主键的值。
在比对壁纸时，受限于特征主键的尺寸，R1×R2这个值越大比对时精确度越高，但是会带来计算消耗。故在比对，相近的壁纸资源可以使用特征辅助键进行辅助。本实施例使用壁纸资源的主色调值进行辅助，辅助键有多种选择，具有可替代性。选用主色调是因为这个值被视效定义成一个在壁纸改变时应用到软件的一个特征值。故在此处选用这个，利用已有便利。
如图9所示，在一实施例中，获取壁纸资源中壁纸的主色调，可以包括：
步骤901，获取缩放后壁纸的调色板对象；
其中，通过输入的缩放壁纸资源获取调色板对象P Target。
步骤902，分别计算所述调色板对象中红、绿、蓝三种颜色的均值，得到缩放后壁纸的主色调。
其中，遍历P Target，获取R B、G B、B B。同理可得，G B与B B。
R B＝∑Color.red(P)
分别计算所述调色板对象中红、绿、蓝三种颜色的均值，即R B、G B、B B分别除以像素的个数，组成壁纸的主色调C Main。
其他壁纸相关特征信息，除了C Main，在这个计算过程还计算其他几个值，这些值，与壁纸特征比对无关。将用于壁纸生效后视效展示用。这些值可以包含：C Fore(前景文字颜色)、C Status(状态栏颜色)，作为特征附加键。
另外，所述特征信息可以还包括自定义特征键。
可以从计算壁纸的数据源处解析是否有自定义的键值，作为自定义特征键。这些键值与壁纸的特征比对无关，将用于壁纸生效后视效的关联修改。
在一实施例中，自定义特征键，来源于预先设定的配置文件。
如图10所示，在一实施例中，所述方法还可以包括：
步骤1000，获取所述壁纸资源中壁纸的分类属性信息，存入特征数据库中。
在此步骤中，解析所有资源的分类属性值，用于统计用户壁纸使用偏好，用于推荐壁纸时使用。
如图11所示，在一应用实例中，所述步骤200可以包括如下子步骤：
步骤1101，获取壁纸资源。
其中，扫描出移动终端中所有可以管理的壁纸资源。
步骤1102，对壁纸资源的序列进行调整。
也即，将已经获取的壁纸资源进行排序。
步骤1103，格式化壁纸资源。
本步骤中，将所述壁纸资源中壁纸的尺寸缩放成目标壁纸尺寸。
步骤1104，获取壁纸资源中壁纸的特征信息。
其中，可以通过计算获取壁纸资源中壁纸的特征主键、特征辅助键和特征附加键，还可以获取自定义特征键和壁纸分类属性信息。
步骤1105，将壁纸资源的信息存入特征数据库中。
将特征主键、特征辅助键、特征附加键以及自定义特征键存储于特征数据库。特征数据库的主键为壁纸资源的资源标识，这个标识为统一管理。此处将壁纸的唯一标识符定义为ID Wallpaper。
如图12所示，在一实施例中，所述切换信息包括待切换壁纸的标识，所述步骤110，包括：
步骤1201，监听系统广播，获取所述待切换壁纸的标识。
其中，可以通过注册系统广播进行监听。
步骤1202，确定当前壁纸的标识与所述待切换壁纸的标识不一致，根据所述待切换壁纸的标识确定待切换壁纸。
其中，根据所述待切换壁纸的标识确定待切换壁纸，则可以获得待切换壁纸的尺寸、像素值等参数，以进行特征信息的提取。
图12的实施例描述方案的触发流程与触发时机，是整个方案被执行的时机描述。触发动作发生在用户点击UI界面触发了壁纸变化之后。
如图13所示，在一应用实例中，步骤110可以包括如下子步骤：
步骤1301，注册系统广播，"android.intent.action.WALLPAPER_CHANGED"；并初始化监控类，此处将当前壁纸在系统中的标识号记录，记为ID cache。
步骤1302，等待系统广播。在接收到系统广播时，获取当前的ID sys，执行1303，若没有系统广播，则继续监听。
步骤1303，将ID sys与ID cache进行比较，若相同，则返回执行步骤1302，若不同，执行步骤1304；
步骤1304，确定待切换壁纸，通知进行待切换壁纸的特征值提取。
步骤120中，获取待切换壁纸的特征信息，与获取壁纸资源中壁纸的特征信息类似，可以参照步骤200以及图3～图9执行。其中，获取的特征信息为特征主键和特征辅助键，无需获取特征附加键和自定义特征键。另外，待切换壁纸的信息来源于调用系统接口。
如图14所示，在一实施例中，所述将所述待切换壁纸的特征信息与特征数据库中壁纸的特征信息进行比对，确定所述特征数据库中与所述待切换壁纸匹配的壁纸，可以包括：
步骤1401，将所述待切换壁纸的特征信息与特征数据库中壁纸的特征信息进行比对；
步骤1402，确定比对的结果满足第一预设条件，将所述特征数据库中满足第一预设条件的壁纸作为与所述待切换壁纸匹配的壁纸；结束流程。
步骤1403，确定比对的结果满足第二预设条件，将所述特征数据库中满足第二预设条件的壁纸添加在备选列表中；
步骤1404，确定在特征数据库中没有满足第一预设条件的壁纸，选择备选列表中满足第三预设条件的壁纸作为与所述待切换壁纸匹配的壁纸。
其中，在一实施例中，所述第一预设条件为：待切换壁纸的特征主键和特征数据库中壁纸的特征主键的距离差小于最小主键阈值，且待切换壁纸的特征 辅助键和特征数据库中壁纸的特征辅助键的距离差小于最大辅助键阈值；
所述第二预设条件为：待切换壁纸的特征主键和特征数据库中壁纸的特征主键的距离差小于最大主键阈值；
所述第三预设条件为：在备选列表中，与待切换壁纸的特征主键的距离差最小，且与待切换壁纸的特征辅助键的距离差小于最小辅助键阈值；或者，在备选列表中，与待切换壁纸的特征主键的距离差最小，且与待切换壁纸的特征辅助键的距离差小于最大辅助键阈值，且与待切换壁纸的特征主键的距离差小于中间主键阈值。
如图15所示，以一个应用实例说明比对的过程，包括如下步骤：
步骤1501，将所述待切换壁纸的特征信息F C与特征数据库中壁纸的特征信息F I进行循环比对；
其中，将F I的特征主键的值与F C的特征主键的值比对，计算求得两者的距离差D diff作为特征主键的距离差。
其中，将F I的特征主键的值与F C的特征主键的值比对逐位比较，不同时，D diff加1。
另外，可能还需要计算特征辅助键的距离差A Diff，其计算方法为：
Figure PCTCN2019097630-appb-000001
Figure PCTCN2019097630-appb-000002
其中，
Figure PCTCN2019097630-appb-000003
分别为待切换壁纸的主色调中红、绿、蓝的值，
Figure PCTCN2019097630-appb-000004
Figure PCTCN2019097630-appb-000005
分别为特征数据库中壁纸的主色调中红、绿、蓝的值。
步骤1502，判断待切换壁纸的特征主键和特征数据库中壁纸的特征主键的距离差D diff是否小于最小主键阈值M min，如果是，则执行步骤1503，否则执行步骤1505；
步骤1503，判断待切换壁纸的特征辅助键和特征数据库中壁纸的特征辅助键的距离差A Diff是否小于最大辅助键阈值C max，如果是，则执行步骤1804，否则执行步骤1801；
步骤1504，确定匹配，返回待切换壁纸对应的标识，结束流程。
步骤1505，判断待切换壁纸的特征主键和特征数据库中壁纸的特征主键的距离差D diff是否小于最大主键阈值M max，是则执行步骤1506，否则执行步骤1501；
步骤1506，将所述特征数据库中当前比对的壁纸添加在备选列表中；
所述备选列表可以采用数组A F。
步骤1507，在循环比对完毕后，获取备选列表中与待切换壁纸的特征主键的距离差最小的壁纸；
本步骤中，在数组A F中查找最适合的壁纸信息。遍历A F在其中查找色差最小的壁纸特征信息。也即D diff最小所对应的特征数据库中的壁纸。
步骤1508，判断待切换壁纸的特征辅助键和特征数据库中壁纸的特征辅助键的距离差A Diff是否小于最小辅助键阈值C min，是则执行步骤1804，否则执行步骤1509；
步骤1509，判断待切换壁纸的特征主键和特征数据库中壁纸的特征主键的距离差D diff是否小于中间主键阈值M Media，且判断待切换壁纸的特征辅助键和特征数据库中壁纸的特征辅助键的距离差A Diff是否小于最大辅助键阈值C max，是则执行步骤1504，否则执行步骤1510；
步骤1510，确定没有匹配的壁纸资源。
所述步骤130中，按照所述匹配的壁纸对应的特征信息进行壁纸切换。
通过上述步骤，可以避免由于多线程切换，壁纸设置来源众多、应用自身逻辑等，可能会导致应用中记录的壁纸状态与系统中被设置的壁纸状态呈出现不一致的情况。另外，目前，主流的设置壁纸的流程，在用户选择一张壁纸后通常要有用户再次确认的过程，这个过程人为使得设置壁纸的过程被拉长，用户不能即刻查看自己的壁纸应用到系统中的状态。通过本公开实施例，无需用户再次确认的过程，实现了所见即所得。
在一实施例中，按照所述匹配的壁纸对应的特征信息包含的特征附加键和自定义特征键中的至少之一进行壁纸切换。
其中，所述自定义特征键的优先级高于特征附加键的优先级。
本公开实施例使用所述匹配的壁纸对应特征附加键和自定义特征键中的至 少之一进行壁纸切换，可以将辅助视效信息(例如，前景色、状态栏颜色等)应用到应用中，这样，能让应用呈现更适合的视觉效果。
如图16所示，在一实施例中，还包括：
步骤1600，确定所述特征数据库中没有与所述待切换壁纸匹配的壁纸，按照所述待切换壁纸的特征信息进行壁纸切换。
如果当前特征数据库中没有对应的壁纸信息。则界面的视效特征将直接使用依据步骤120计算得到的F C相关特征。并将F C对应的分类相关信息进行存储用于统计用户偏好壁纸。
如图17所示，为本公开应用实例的UI展示示意图，其中，用户在壁纸选择页面随意选择，例，选择图中的壁纸n-1，选中的壁纸将被实时的应用到系统中。同时，特征附加键与自定义特征键将被应用到相关的软件中。并将关联数据进行保存与同步。
如图18所示，所述方法还可可以包括：
步骤1800，按照壁纸的特征信息、内容信息和分类属性信息中的至少之一推荐壁纸。
其中，壁纸的特征信息来源于前述获取特征信息的步骤。此处可以采用壁纸的主色调。可以把主色调划分为几个类别，分别设置类别标签，
分类属性信息来源于壁纸资源的预设分类，可以从初始化的数据中获取。内容信息可以来源于预设，也可以来源于本地人工智能(Artificial Intelligence，AI)学习模型，可以采用已有的AI图片分类模型实现，此处不再赘述。
如图19所示，在一实施例中，步骤1800包括：
步骤1901，按照壁纸的主色调、内容信息和分类属性信息中的至少之一统计用户偏好信息；
其中，统计用户所使用的壁纸的分类属性信息、内容信息和主色调中每个分类的概率，获取概率最高的三个分类标签，进行缓存。
步骤1902，按照所述用户偏好信息调整预置的壁纸资源中壁纸的显示顺序，填充推荐位。
其中，可以设置推荐的优先级为：分类属性信息优先级最高，内容信息次之，主色调优先级最低。
如图20所示，在一实施例中，所述方法还包括：
步骤2000，确定从预置的壁纸资源中无法填满推荐位，则从服务器按照所述用户偏好信息获取壁纸资源，填充推荐位。
本公开实施例根据壁纸的特征信息与服务器进行交互，为用户推荐最符合用户使用习惯的壁纸资源，可以提升用户对美化资源的满意程度。
如图21所示，本公开应用实例的推荐过程包括：
步骤2101，按照壁纸的特征辅助键、内容信息和分类属性信息统计用户偏好信息；
将三个数据类型的数据进行单独处理，得出概率最高的三个偏好标签，并记录百分比。
针对特征辅助键，可以来源于调色板的分类，这部分可以参考辅助键获取部分。每张壁纸记录三个颜色信息。遍历所有数据获取均值前三位用来估算偏好类型。
针对壁纸分类属性信息，其标签为壁纸分类标签，来源于预设(下载的资源来源于下载类别)，同样统计出现的前三个类别用于估算，并记录百分比。
针对壁纸内容信息，其标签为壁纸内容标签，同样统计出现的前三个类别用于估算，并记录百分比。
步骤2102，生成标签列表；
步骤2103，判断预置的壁纸资源中是否有标签列表对应的壁纸，如果是，则执行步骤2104；
针对三类数据，壁纸分类标签优先级最高，即此类别数据最为有效，所以在推荐过程中以此类型有优先级最高依次为壁纸内容。在服务器推荐类别内容多余推荐位时，将使用辅助键(主色调进行筛选)。
步骤2104，按照推荐标签调整预置的壁纸资源的显示顺序；
步骤2105，判断是否填满了推荐位，若是，则执行步骤2108，若否，则执 行步骤2106；
步骤2106，从服务器按照所述用户偏好信息获取壁纸资源；
步骤2107，判断是否填满推荐位，若是则执行步骤2108，若否，则执行步骤2102。
本应用实例中，通过预置资源的特征信息统计与用户应用壁纸信息的融合通过与服务器交互，为用户推荐符合用户偏好的壁纸资源。
如图22所示，本公开实施例还提供一种壁纸管理的装置，可以包括：
