图像识别或匹配 [英] image recognition or matching

问题描述

大家好，

我需要您的帮助才能在vb.net中执行代码以将图像与数据库中的其他图像进行匹配.
我的数据库由图像和图像名称组成.
我对数据库中的图像进行预处理，然后将其设为黑白.
我需要代码来比较插入的图像与数据库中的图像
查找数据库中是否有类似的数据库.

我了解我需要将图像分为9部分
然后将每个部分与像素的颜色和位置进行比较，并根据预定百分比接受这些部分，我需要重新划分中心部分并重新绘制比较，但是我现在不知道如何划分图像并使此代码
请帮助我尽快这样做.

非常感谢

Hi every body,

I need your help to do code in vb.net to match image with other images in database.
I have database consist of images and name of image.
I preprocess image in database and let it black and white.
I need code to compare inserted image from out side with image in database
to find if there is similar one in database.

I understand that i need to divide image to 9 part
and compare each part with color and position of pixel and accept thid partion according to predetermine percentage, and I need to re-divide the central part and repaint the comparison but i don''t now how to divide image and make this code
please help me to do this as soon as possible.

Thanks a lot

推荐答案

如果图像的像素大小相同，则只需计算图像的校验和并将其存储在数据库中即可.检索匹配项时，您将计算该图像的校验和并进行搜索.这将比匹配图像本身快得多.您可以将完整的图像与绝对确定的结果进行比较.

祝你好运！

If the images should be the same pixel by pixel then simply calculate a checksum of the picture and store it in the database. When retrieving a match you calculate the checksum of that image and search with that. This will be a lot faster then matching the images itself. You can do a complete image compare with the results you get to be absolutely sure.

Good luck!

感谢您的帮助
但是我尝试执行代码以检查两个图像中像素的位置并接受70％的像素并计算两个图像中的白色，如果两个图像中的相似度都达到75％，则接受白色

thanks for your helping
but i try do code to check the position of pixels in both image and accept it in 70 % and count the white color in both images then accept it if they have 75 % similar in both images

如果您已完成操作，请给我您的源代码....我的邮件ID为[e-mail]
