[tesseract-ocr] Re: Unrecognized lines using psm 3

2016-09-02 Thread fuzzy7k

I found the function that puts everything on the table, with regard to the 
scrollview blob debug window...
ccstruct/blobbox.cpp:
ScrollView::Color BLOBNBOX::TextlineColor(BlobRegionType region_type,
  BlobTextFlowType flow_type) {
  switch (region_type) {
case BRT_HLINE:
  return ScrollView::BROWN;
case BRT_VLINE:
  return ScrollView::DARK_GREEN;
case BRT_RECTIMAGE:
  return ScrollView::RED;
case BRT_POLYIMAGE:
  return ScrollView::ORANGE;
case BRT_UNKNOWN:
  return flow_type == BTFT_NONTEXT ? ScrollView::CYAN : ScrollView::
WHITE;
case BRT_VERT_TEXT:
  if (flow_type == BTFT_STRONG_CHAIN || flow_type == BTFT_TEXT_ON_IMAGE)
return ScrollView::GREEN;
  if (flow_type == BTFT_CHAIN)
return ScrollView::LIME_GREEN;
  return ScrollView::YELLOW;
case BRT_TEXT:
  if (flow_type == BTFT_STRONG_CHAIN)
return ScrollView::BLUE;
  if (flow_type == BTFT_TEXT_ON_IMAGE)
return ScrollView::LIGHT_BLUE;
  if (flow_type == BTFT_CHAIN)
return ScrollView::MEDIUM_BLUE;
  if (flow_type == BTFT_LEADER)
return ScrollView::WHEAT;
  if (flow_type == BTFT_NONTEXT)
return ScrollView::PINK;
  return ScrollView::MAGENTA;
default:
  return ScrollView::GREY;
  }
}


and some detailed description on what it all means...

// The possible region types of a BLOBNBOX.
// Note: keep all the text types > BRT_UNKNOWN and all the image types less.
// Keep in sync with kBlobTypes in colpartition.cpp and BoxColor, and the
// *Type static functions below.
enum BlobRegionType {
  BRT_NOISE,  // Neither text nor image.
  BRT_HLINE,  // Horizontal separator line.
  BRT_VLINE,  // Vertical separator line.
  BRT_RECTIMAGE,  // Rectangular image.
  BRT_POLYIMAGE,  // Non-rectangular image.
  BRT_UNKNOWN,// Not determined yet.
  BRT_VERT_TEXT,  // Vertical alignment, not necessarily vertically 
oriented.
  BRT_TEXT,   // Convincing text.
  BRT_COUNT   // Number of possibilities.
};

// BlobTextFlowType indicates the quality of neighbouring information
// related to a chain of connected components, either horizontally or
// vertically. Also used by ColPartition for the collection of blobs
// within, which should all have the same value in most cases.
enum BlobTextFlowType {
  BTFT_NONE,   // No text flow set yet.
  BTFT_NONTEXT,// Flow too poor to be likely text.
  BTFT_NEIGHBOURS, // Neighbours support flow in this direction.
  BTFT_CHAIN,  // There is a weak chain of text in this direction.
  BTFT_STRONG_CHAIN,   // There is a strong chain of text in this direction.
  BTFT_TEXT_ON_IMAGE,  // There is a strong chain of text on an image.
  BTFT_LEADER, // Leader dots/dashes etc.
  BTFT_COUNT
};


So, it thinks there is an image in there somehow and all I did to fix it 
was to bypass an if statement.

Did you consult its documentations? Look for "confidence" in TessAPI class.

[tesseract-ocr] Tesseract ocr recognition rate

2016-09-02 Thread Suin You

There are 2 questions.

I'm only using tess4j for JAVA. It may not have the function that gets the 
result's accuracy rate.
can I know the tesseract result accuracy rate?


And, 
How do I distribute the Graphic Text and 2D Graphic Image like logo or 
emblem?
Sometimes the tesseract recognized 2D graphic image like emblem.

Any suggestions?
