数字图像处理工具 [英] digital Image processing tool

问题描述

大家好，
实际上我想研究数字图像处理来分析一些有趣的
图片的特征. capcha检测，边缘检测，物体/面部检测，图像旋转，降噪]
并想研究一些数学模型像图像频域转换[通过FFT，DTFT，拉普拉斯变换等].我想看看它在应用序列后如何影响图像的过程[无需从头开始编写所有内容].

因此，我需要一些软件(不是Matlab或photoshop等非常大的软件)或API(在Java，C ++，C#中)，可以在其中测试所有这些数学模型.我尝试了很多软件，但是除了matlab之外，我没有这些软件功能或功能随处可见.

我不确定JAI [Java Advanced Imaging]是否具备所有这些功能.如果是，那么它会很棒[如果是，那么它上需要一些教程].否则，任何开源api或更糟糕的情况是，任何软件或工具都足够了.

如果有人可以在此图像处理和文档方面提供任何有用的资料
的api/软件，那么我会非常的开心.

Hi All,
Actually I want to study digital image processing to analyze some interesting
features of images.[eg. capcha detection,edge detection,object/face detecting,image rotation,noise reduction]
and want to study some mathematical model like image frequency domain conversion[by FFT,DTFT, Laplace transform etc.]I want to see how its affecting an image after applying a sequence of those process[without writing everything from scratch].

So I need some software [not something very huge like Matlab or photoshop] or API[in Java ,C++,C#] where I can test all this mathematical models.I have tried so many software but excepting matlab I didn''t got those functions or functionality any where.

I am not sure if JAI[Java Advanced Imaging] have all this.if yes then it will be great[if yes then want some tutorials on it].Otherwise any open source api or , in worse case any software or tool will be enough.

If anybody can give any helpful materiel on this image processing and documentation
of that api/software then I''ll be very much great full.

推荐答案

如果处理了验证码检测，我会感到惊讶，但是对于其余任务-我倾向于研究OpenCV( Open [source] Computer Vision)

I''d be amazed if it handled captcha detection, however for the remaining tasks - I''d be inclined to look into OpenCV (Open[source] Computer Vision)

嗨shankha2010

如果您想学习图像处理/计算机视觉，建议您阅读一些有关数字图像处理的基本书籍.数值方法.例如Rafael C的Digital Image Processing是一个很好的开始.但是要学习用C或C ++实现它还需要花费一些时间.因此，您可以使用Wolfram mathematica或Matlab之类的工具.它将帮助您节省理解概念的时间.(或建立一个库自己的东西，每当您学习新东西时

OpenCV是一个很好的库，但是我建议您首先学习基础知识.

Hi shankha2010

If you want to learn image processing/computer vision, i suggest you to read some basic books on digital image processing & numerical methods. for example Digital Image Processing by Rafael C is a good start. But it will take time to learn things also to implement it in C or C++.. So for that you can use tools like Wolfram mathematica or Matlab.It will help you to save your time in understanding the concepts.( or make a library of your own , whenever you learn some thing new)

OpenCV is a good library,But i suggest you to learn basics first.

Hopes this helps.
