具体实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白,以下结合附图和实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明的保护范围,并不用于限定本发明的保护范围。
实施例一
图1是本发明提出的图像色彩识别方法的流程图。该方法包括:
S1,对图像区域进行RGB值采样分析。
对选中图片的整个图像区域进行RGB值采样分析。可以理解,本实施例的图像色彩识别方法可以用于智能手机、平板电脑等具有智能处理功能的设备中。RGB值采样分析属于现有技术手段,在此不再赘述。
进一步地,对选中图片的部分区域进行RGB值采样分析;
进一步地,对其它显示终端上的图像区域进行RGB值采样分析,并通过通信信道传输该采样分析结果;
进一步地,对任一显示终端上的图像区域进行RGB值采样分析后,将该采样分析结果上传至云端服务器接受后续处理。
S2,根据RGB值以及色彩差异度阈值将图像区域划分为至少两个色块区域。
色彩差异度是指不同的色彩占总色彩的比例值。例如,若经分析得到图像区域内一共有红、黄、蓝、绿、紫、白六种颜色,这六种颜色所占的范围在整个图像区域的比例分别是10%,19%,11%,22%,28%,10%。当色彩差异度阈值设置为10%,且根据色彩差异度大于该预设阈值时确定为上述色块区域时,相应地,得到黄色色块区域、蓝色色块区域、绿色色块区域以及紫色色块区域。
进一步地,根据图像色彩识别操作的精准度需求确定相应的色彩差异度阈值,例如,若需要较高的精准度,则降低该色彩差异度阈值,反之则调高该色彩差异度阈值。
进一步地,同时对一个或多个图像区域进行色块区域划分操作,使用相同或不同的色彩差异度阈值作为划分依据。
S3,对色块区域执行色块轮廓标识操作、文字标识操作、蒙版标识操作以及合成标识操作。
具体地,执行以下操作,以实现对图像区域的图像色彩识别:
a,在各个色块区域的边界线上设置色带,以实现对各个色块区域的色彩识别;
b,将各个色块区域的颜色信息发送至云端服务器,通过云端服务器对颜色信息进行匹配查询,并根据返回的匹配查询结果,通过文字在相应的色块区域中予以标识识别;
c,在各个色块区域中,选定任一色块区域作为目标色块区域后,将其它区域作蒙版处理,从而使得该选定的色块区域更容易识别;
d,在各个色块区域中,合并颜色相近的色块区域,或者合并颜色相近的颜色区域,从而使得图像区域内的颜色种类较为单一,便于识别。
本实施例的有益效果在于,首先,通过对图像区域进行RGB值采样分析,然后,根据RGB值以及色彩差异度阈值将图像区域划分为至少两个色块区域,最后,对色块区域执行色块轮廓标识操作、文字标识操作、蒙版标识操作以及合成标识操作。实现了对图像区域进行轮廓化、文字化、蒙版化以及单一化处理,提高了用户对图像区域的色彩辨识度,便于视觉障碍用户更轻松地识别图像区域内的色彩,避免了因为颜色混淆所带来的困扰,增强了生活观感和用户体验。

S311,将任一颜色占图像区域的比例值大于第一预设颜色比例值的图像区域作为第一待处理区域。
如上例所述,该第一预设颜色比例值可以是色彩差异度阈值,通过该比例值划分得到多个待处理区域,并将该多个待处理区域统称为第一待处理区域。
S312,分析处于第一相邻关系的第一待处理区域。
在多个待处理区域中,由于可能存在相邻关系的待处理区域,因此,分析确定处于相邻关系的待处理区域,以及相邻的位置信息。
S313,根据第一相邻关系确定第一待处理区域之间的第一边界线。
根据第一相邻关系以及上述步骤中相邻的位置信息确定各个待处理区域相邻的边界线,并将各个边界线统称为第一边界线。
S314,沿第一边界线的预设像素宽度填充预设标识色,生成色块轮廓标识。
具体地,确定预设的像素宽度,例如,设置两个像素宽度作为轮廓标识带的宽度,即,沿第一边界线的两个像素宽度内填充预设的标识色形成轮廓标识带。
进一步地,根据不同的边界线以及边界线两侧的颜色值确定色值差较大的标识色作填充;
进一步地,根据不同的应用场景确定预设像素宽度,例如在较高分辨率下选用较高的预设像素宽度,反之则选用较低的预设像素宽度。
本实施例的有益效果在于,通过将任一颜色占图像区域的比例值大于第一预设颜色比例值的图像区域作为第一待处理区域,并分析处于第一相邻关系的第一待处理区域,然后,根据第一相邻关系确定第一待处理区域之间的第一边界线,最后,沿第一边界线的预设像素宽度填充预设标识色,生成色块轮廓标识。实现了通过轮廓标识颜色带对色块区域的准确划分,便于用户通过轮廓标识带进行色块区域的视觉划分和视觉识别。提高了用户对色块区域的识别度,增强了色块区域识别的视觉观感。
实施例三

S322,分析处于第二相邻关系的第二待处理区域。
如上例所述,在多个待处理区域中,由于可能存在相邻关系的待处理区域,因此,分析确定处于相邻关系的待处理区域,以及相邻的位置信息。
S323,根据第二相邻关系确定第二待处理区域之间的第二边界线。
根据第二相邻关系以及上述步骤中相邻的位置信息确定各个待处理区域相邻的边界线,并将各个边界线统称为第二边界线。
S324,获取由第二边界线围成的图案形状。
例如,该图案形状为圆形,进一步地,该图案行为为水果类的圆形。
S325,将图案形状以及第二待处理区域发送至云端。
可以理解,云端服务器存储有各类图像形状的特征信息,该特征信息是对各类图像形状的特征提取的合集。
S326,通过云端识别图案形状的物品种类以及匹配与物品种类对应的颜色属性信息。
通过提取图案形状的特征信息,然后根据提取的特征信息在云端服务器中进行查询匹配,查找到与该特征信息相对应的物品种类,同时,根据该物品种类确定对应的颜色属性信息。
S327,返回物品种类以及颜色属性信息,并通过文字在第二待处理区域内予以标识。
具体地,根据物品种类确定种类信息,生成种类文字标识,根据颜色 属性信息确定颜色信息,生成颜色文字标识。
例如,通过拍照,识别当前水果是什么品种,然后再对该水果的颜色或成色进行匹配,如果在新鲜状态的正常范围内,则通过文字标识该水果是新鲜的,否则通过文字标识为不新鲜。
本实施例的有益效果在于,通过将任一颜色占图像区域的比例值大于第二预设颜色比例值的图像区域作为第二待处理区域,然后分析处于第二相邻关系的第二待处理区域,根据第二相邻关系确定第二待处理区域之间的第二边界线,获取由第二边界线围成的图案形状,将图案形状以及第二待处理区域发送至云端,通过云端识别图案形状的物品种类以及匹配与物品种类对应的颜色属性信息,最后,返回物品种类以及颜色属性信息,并通过文字在第二待处理区域内予以标识。实现了通过将色块区域的颜色特征发送至云端服务器进行识别,从而根据返回的结果予以文字标识。便于用户通过文字识别提高对图像区域的视觉划分和视觉识别。提高了用户对色块区域的识别度,增强了色块区域识别的视觉观感。
实施例四

如上例所述,该第三预设颜色比例值可以是色彩差异度阈值,通过该比例值划分得到多个待处理区域,并将该多个待处理区域统称为第三待处理区域。
S332,确定任一第三待处理区域作为识别目标区域。
可以理解,该目标区域可以是一个或多个第三待处理区域内的色块区 域。
S333,通过预设透明度的蒙版覆盖图像区域内除目标区域外的其它区域。
例如,对所点击的目标区域进行RGB颜色分析,在点击目标区域上的相似色彩上,颜色不变,而非点击目标区域的色彩上,则会覆盖50%透明度的黑色模板,以提高目标区域的标识度。
S334,高亮显示目标区域。通过高亮显示目标区域,进一步地提高目标区域的标识度。
本实施例的有益效果在于,通过将任一颜色占图像区域的比例值大于第三预设颜色比例值的图像区域作为第三待处理区域,然后,确定任一第三待处理区域作为识别目标区域,最后,通过预设透明度的蒙版覆盖图像区域内除目标区域外的其它区域,并高亮显示目标区。实现了通过蒙版标识非目标区域,从而使得目标区域更容易识别。同时,采用高亮显示目标区域,更进一步地提高了用户对目标区域的视觉划分和视觉识别。提高了用户对目标区域的识别度,进一步增强了对目标区域进行识别的视觉观感。

进一步地,根据用户的红绿色盲或者其它颜色障碍情况确定一种或多种颜色作为合成的标识颜色。
S345,通过至少两种标识颜色标识第四待处理区域。
可以理解,经过将第四待处理区域内的颜色和成为至少两种标识颜色后,该区域内的颜色更容易得到区分和识别。
进一步地,可以执行多次合成操作,例如,首先合成较多的标识颜色,若用户仍然难以识别,则进一步地执行合成操作,直到合成的标识颜色便于用户识别;
进一步地,可以多次更改执行合成操作的标识颜色,根据不用的应用场景(例如不同的背景色)选定该标识颜色,以便于用户识别。
本实施例的有益效果在于,通过将任一颜色占图像区域的比例值大于第四预设颜色比例值的图像区域作为第四待处理区域,在第四待处理区域内,对颜色进行RGB值采样处理,根据采样处理获取色彩分布值,最后根据色彩分布值,将属于同一色系的颜色合成为标识颜色。实现了将待处理区域的颜色单一化,便于用户识别主要的颜色区域,同时,通过多次合成以及多次改变合成颜色,进一步地增强了用户对待处理区域颜色的识别度和识别观感。
