@HsiehYiChia Thank you for you hard work

After reading your replies on issue #6, it is still unclear how to train our own model.
Can you simplify the training process to us.

The exe file can be compiled and executed but didnot show anything in the window,after some seconds I got this: Microsoft C++ Exception: std::length_error .

Debugger takes me to ER.h
struct Node
{
Node(ER v, const int i) : vertex(v), index(i){};
ER vertex;
int index;
vector adj_list;
vector edge_prob;
};

typedef vector < Node > Graph;

In Type def vector < Node > Graph , Node is ambiguous

Hi, You have done a wonderful job. Can you tell me how to train with my own data? Thanks!

Hi!
Thank you for your project!
Maybe the pos and neg is too large to unzip

I want to use text detection function without OCR,but I don't know how to prepare my own neg and pos. Could you tell me how to prepare training data ? Could you update the training data again ?

can any help me out
Thanks

I know it uses the machine classifier to judge non-text.
But i didn't know what does it mean to be “strong” and “weak”?
What are the "strong" and "weak" classifying based on?
I want to learn it and make it better to classify。

My English is no well，maybe you can't easily to read。
Hope to get your reply.

//Chinese 中文
strong和weak分类器是根据什么来判定的？
我想去深入了解一下并把它改进改进。

.\canny_text.exe -icdar
Error: the input file is not opened!!
Error: the input file is not opened!!
Error: the Transition Probability Table file is not opened!!

Btw i also tried to open up an image but same error

Hi, Thank you for your work , Can you tell me The steps of model training more in detail , which function will be used, Thank you

Should the text data and non-text data in the root directory of /res/neg and /res/pos? or they can be put in folders of /res?

Dear HsiehYiChia,

I run the model with the ".\scene_text_recognition.bat -i res\ICDAR2015_test\img_6.jpg" command and I noticed that the result were not the same with the one mentioned. For example I was expecting to see the result1.jpg but the output was the result. Can you tell me how to fix it? Thank you in advance.

I'm new to the image processing filed, would you please help me to answer this problem?

Hello,

I've successfully compiled the solution and I've been able to test it with some images. However, when passing a video file as argument, it seems that it only process one frame, the first one. I am using as it is written in the docs: "scene_text_recognition.exe -v videofile.name". Am I doing something wrong?

Thanks!
Ana
