Hi Zdenko, "More complex solution" is giving better results in detecting text than earlier one. In addition it points out the layout of where the text is.
But I don't have clear idea as to what this script is doing better compared to earlier one. Please help me in understanding what the following methods are for: TessBaseAPISetPageSegMode TessBaseAPIGetComponentImages TessBaseAPISetVariable Also, What are Page Segmentation Modes? What are Page Iterator Levels? What is OSD?
