Description

一种图像的存储处理方法 技术领域:
本发明涉及一种图像的存储处理方法, 属于图像处理技术领域。
背景技术:
目前现有的图像存储处理方法是将组成图像的所有帧的每一帧的像素完 整不漏地进行存储处理,这种图像的存储方法的主要缺点是图像的存储信息量 庞大, 存储时间长, 且存储出来的图像文件的体积过大, 即存储出来的图像文 件的字节数非常大, 这样图像的转输和解读显示的时间也长, 导致效率低下。 发明内容:
本发明的目的是为了克服上述的缺点而提供了一种高效、简捷的图像存储 处理方法。
本发明的构思是在图像存储处理的过程中,当后一帧图像与前一帧的处于 相同位置的像素相同时,则避免将其重复存储从而达到减少图像存储信息量的 目的, 若图像的后一帧的某像素与前一帧图像的处于相同位置的像素是相同 的, 则这两个像素被定义为相同像素从而成为不需要被存储处理的对象, 即对 此相同像素不予存储处理;若图像的后一帧的某像素与前一帧图像的处于相同 位置的像素有差别,则后一帧的该像素被定义为不相同像素从而成为需要被存 储处理的对象, 这样就极大地减少了图像信息的存储处理量, 从而也极大地减 小了图像的储存空间。 同时将新生成的图像文件建立新的相关时间序列; 在 图像的解读和显示时将后一帧所有不同像素代替前一帧相同的同位像素的内 容并予以显示, 以此类推, 从而得到变化后的图像。 本发明的优点在于: 图像的存储处理的信息量大大减少且存储时间短, 极 大地减小了图像的储存空间,存储出来的图像文件的体积即图像文件的字节数 大大减小, 提高了图像的存储处理、传输和解读显示的效率, 具有较强的实用 价值。
附图说明:
图 1是本发明所述一种图像的存储处理方法的工作原理图,
其中, (a) 为需要存储处理的图像的第一帧 Tl, (b) 为需要存储处理的图 像的第二帧 T2。
具体实施方式
下面结合附图和具体实施例对本发明所述一种图像的存储处理方法作进 一歩详细的说明。 本发明包括以下歩骤:
1. 图像编码:通过图像存储处理软件对需要存储的图像的各帧依照其产 生和其后被展示的先后顺序进行顺序编码, 例如: 第 1帧为图像 τι, 第二帧为图像 Τ2, ……, 第 η帧为图像 Τη;
2. 图像像素编码:通过图像存储处理软件对各帧图像包含的各个像素按 照其在图像中的位置进行地址编码, 如图 1所示: 第一帧图像 T1的 像素 Tl (XI, Yl )、像素 Tl (Χ2, Υ2)、像素 Tl (Χ3, Υ3)和像素 Tl (Χ4, Υ4), 第二帧图像 Τ2的像素 Τ2 (Χ1, Yl )、 像素 Τ2 (Χ2,Υ2)、 像素 Τ2 (Χ3,Υ3 ) 和像素 Τ2 (Χ4, Y4);
3. 图像像素比较:通过图像存储处理软件对图像 Τη和图像 Τη+1中位于 相同像素位置的像素 Tn (Xm,Ym) 和 Tn+l (Xm,Ym) 进行比较如果两者 差值小于或等于此阀值, 则确定被比较的两个像素 Tn (Xm,Ym ) 和 Tn+l (Xm,Ym)为相同像素; 如果两者之间差值大于设定的阀值, 则将 后者 Tn+l (Xm,Ym) 则被定义为不同像素;
4. 对在图像 Tn+1中对于与图像 Τη中处于相同像素位置的相同像素不进 行存储处理;对在图像 Tn+1中与图像 Tn中处于相同像素位置的不同 像素 Tn+1 (Xm, Ym)进行存储处理, 即在这种情况下以下一帧的不同像 素来代替上一帧处于相同像素位置的像素,从而生成一帧新的已经产 生了变化的图像, 则新生成的图像组成如下:
i. 第一帧 = 第一帧,
ϋ. 第二帧 = 第一帧 + 第二帧与第一帧的处于相同像素位置的各 不同像素,
iii. 第三帧 =第二帧 + 第三帧与第二帧的处于相同像素位置的各 不同像素,
iv. 第四帧以此类推……。
同时通过图像存储处理软件将新生成的图像文件建立新的相关时间序列; 在图像的解读和显示时通过图像存储处理软件将后一帧所有不同像素代替前 一帧相同的同位像素的内容并予以显示, 以此类推, 从而得到变化后的图像。
本发明不限于上述实施例,对于本领域技术人员来说,对本发明的上述实 施例所做出的任何改进或变更都不会超出仅以举例的方式示出的本发明的实 施例和所附权利要求的保护范围。
