Hi,

Hi,

I want to make a software that scans an Image (admission form) and identifies the Text within its fields. And puts them in some File. I am doing this in C++. I have some little experience with opencV but not as much as is required to do the OCR thing. So I realized a solution. Call an external Command Line tool which converts an image to text. Then my program just needs to fetch the required data from the text file. Its  kind of funny I believe, I don't actually know if I have any other options in hand. So my question is:

"Is there any API sort of thing that can be called from my program to convert an image to text?"

Hi,

I am a student of CSE. I am currently beginning to program with java using netbeans. I know some C++. I am now doing a project where I have to call some other program, from within the java program.

How can we access the array elements? I am working on loops but there is a problem in the code, every time I have to initialize “I” to the next value when I want to store any value in the array. Is it right way to assign values to an array? Int marks[5]; Int i=1; Marks[i]=5; i=2; Marks[i]=4; If yes then tell me how can I access the values from the array when I want to display the value of specific index?
