指纹特征提取项目帮助 [英] Help in Fingerprint Feature Extraction Project T.T

问题描述

我是Viola，我是C#的新生.仅供参考，我目前正在从事指纹特征提取项目.

Hi, I''m Viola, I''m a total freshie to C#. FYI, I''m currently working on a fingerprint feature extraction project.

我想用Microsoft Visual C#Express Edition编写图像处理程序.但是，事情是...我什至不知道该如何开始... T.T

I want to write an image processing program with microsoft visual C# express edition. But, the thing is... i don''t even know how to start... T.T

我有一些 8位深度(256种灰色)， TIFF 格式和单色(灰度)的指纹图像.

I have some fingerprint images in 8 bit depth (256 types of grey) ,TIFF format , and monochrome(grayscale).

以前，我认为我可以将灰度图像像素转换为十六进制数字以进行进一步处理. (例如)

Previously, i thought i could convert the grayscale image pixels to hexadecimal numbers for further processing. (see Eg)

__________________________________________________________________

例如.

0 =黑色，255 =白色，1-254 =黑色和白色之间的中间灰色

0= black, 255= white , 1-254= intermediate grey between black and white

因此，对于灰度图像

我希望生成的代码像这样:

i want the generated code to be like:

0811FF00 ......(以十六进制表示)，其中08 = 8th grey，11 = 17th grey，FF = white和00 = black

0811FF00...... (in hexadecimal), where 08= 8th grey, 11= 17th grey, FF=white, and 00= black

或

00001000000101111111111100000000 .....(二进制代码)，其中00001000 = 8th grey，00010111 = 17th grey，11111111 = white，00000000 = black

00001000000101111111111100000000..... (in binary code), where 00001000= 8th grey, 00010111=17th grey, 11111111= white, and 00000000= black

我请客，这是不可能的...我已经尝试过，以64为基数，以二进制，byte []转换为十六进制，进行各种转换....

I guest it''s impossible... I''ve been tryin, base 64, binary, byte[] to hex, all sort of conversion.... 

有人可以告诉我吗?我如何处理图像?我以为我必须生成一些代码/文件才能进一步处理?我可以对图像进行图像处理(例如gabor滤波，定向图像生成，频率图像生成)吗?

Can someone tell  me how to process an image? I thought i have to generate some code/file to be further processed? Can i just do image processing(like gabor filtering, orientation image generation, frequency image generation)  onto the image?

帮助... TT

推荐答案

这是您关于相同问题的主要文章.您可以只编辑原始问题.不要重复发布相同的问题.我建议您尝试删除重复项，只剩下一个问题(如果可以的话……Code Project有关于可以删除哪些问题的有趣规则).

另外，你甚至知道你想要什么吗?首先，您必须提出一个连贯的问题，否则没人会回答.并尽量简明扼要...尝试提出一个简单的问题，并提供一些背景知识和一些示例代码，而不仅仅是说我完全迷路了，不知道我在说什么"正在做".这是一个如何提问的错误示例:

This is your thrid post of essentially the same question. You can just edit your original question. Do not post the same question repeatedly. I recommend you try to delete the duplicates and leave only 1 question remaining (if you can... Code Project has funny rules about which questions can be deleted).

Also, do you even know what you want? First, you must formulate a coherent question, or nobody will be able to answer it. And try to be concise... try to ask a single question, with a little background and perhaps some code to show an example, and not just say "I''m completely lost and don''t know what I''m doing". Here''s a bad example of how to ask a question:

How do I process an image.
I want to store some bytes in a file.

这是一个如何提出问题的好例子:

Here''s a good example of how to ask a question:

I'm using the built in C# .Net libraries to import
an image that is stored as a 8-bit grayscale TIFF.
How do I access the pixel data so that I can get
numeric values that correspond to the grayscale
color of each pixel in the image?
For example, 0 would correspond to black,
128 would correspond to gray, and 255 would correspond to white.

这也是一个不好的问题，因为通过谷歌搜索可以很容易地找到这些信息(您来这里之前曾在Google上进行过广泛的搜索，不是吗?).如果再次遇到问题，这可能是在后续问题中可能要问的问题:

That is also a bad question, because such information can easily be found by googling for it (you did google extensively before coming here, didn''t you?). Here is what you might ask in a subsequent question, if you get stuck again:

I can't seem to figure out how to convert a
decimal number to a binary number stored in a string.
For example, the decimal number 50 would be converted
to a string that says "30011" (a string containing the binary
representation of the decimal value 50).
Do any of you know how to do that?

顺便说一句，我可能会回答所有这些问题，但是我无法真正分辨出这是否是您想要的.您需要花一些时间来澄清您的问题，然后使用Google搜索，然后自己尝试一些代码，如果您真的无法解决，请在此处发布.但是请具体且清楚.

By the way, I could probably answer all those questions, but I can''t really tell if that''s what you want. You need to spend some time clarifying your questions, then googling them, then trying some code out yourself, then post here if you really can''t figure it out. But please, be specific and be clear.
