How do I reuse an existing Tesseract Engine to improve performance?
I'm using Tesseract for detecting numerical values from the screen where I need it to always be scanning the screen for changes as long as my program is running. This has been working really well, but I've noticed that it is very CPU intensive. While searching for help on this topic, I came across this question here, but I am unsure how to change my code to reuse an existing Tesseract Engine. I'll post sample code below, but in my program I'll need to be scanning 4 different areas of the screen for various numbers, so I have 4 Tesseract Engines right now.
Here is some sample code:
MainClass being looped while the program is active.
var thread_Character_CurrentMana = new Thread(Character.Character_CurrentMana)
{
Name = "thread_Character_CurrentMana",
IsBackground = true
};
thread_Character_CurrentMana.Start();
Character.cs
public static void Character_CurrentMana()
{
CurrentMana = CharacterCurrentMana();
}
private static int CharacterCurrentMana()
{
if (UI.MyCurrentMana_Width == -999999999 || UI.MyCurrentMana_Height == -999999999 ||
UI.MyCurrentMana_PositionX == -999999999 ||
UI.MyCurrentMana_PositionY == -999999999)
return -1;
try
{
using (var memoryImage =
new Bitmap(UI.MyCurrentMana_Width, UI.MyCurrentMana_Height))
{
using (var memoryGraphics = Graphics.FromImage(memoryImage))
{
var _size = new Size(UI.MyCurrentMana_Width, UI.MyCurrentMana_Height);
memoryGraphics.CopyFromScreen(UI.MyCurrentMana_PositionX,
UI.MyCurrentMana_PositionY, 0, 0, _size);
using (var ocr = new TesseractEngine(Program.TesseractDataFolder, "eng",
EngineMode.TesseractAndCube))
{
using (var page = ocr.Process(memoryImage, PageSegMode.SingleWord))
{
var value = 0;
if (int.TryParse(page.GetText(), out value))
{
var _MyCurrentMana = Convert.ToInt32(page.GetText());
return _MyCurrentMana;
}
return -1;
}
}
}
}
}
catch
{
return -1;
}
}
