ROI selection in HTLine Module of VAT

Question asked by lalitha123 on Feb 13, 2015



In the project vat_file_i/o_adsp_bf609,

  • the function MarkLanes in vat_prepare_output.c has an array aHorizon[4] which has x0,y0,x1,y1 for ROI. How are these numbers determined.
  • What is the purpose of CheckHTLineIsThroughRectangle in vat_ht_line_demo.c
  • This module is not giving me a correct output with any other pgm file of same resolution other than the given vat_demo_inp_2.pgm file. Edge detection is working fine but lanes are not being determined in my customized input image file.


Thank you
