Hough Transform

HI 

I use vlib_c66x_3_2_1_0...

After using hough line, I need to ""Inverse mapping"" to my frame...

1. How can I find some information for my problem?

VLIB_houghLineFromList(edgemap, outhoughspace, width, height, (int)k/2 , 267, 267, TableSineBK_Minus80toPlus80resZeroPointSix_Q8, TableCosineBK_Minus80toPlus80resZeroPointSix_Q8, ping, pong, pang, peng );


houghline_max = max_array(outhoughspace,267,267); 

 


2. Whether  values of ""TableCosineBK_Minus80toPlus80resZeroPointSix_Q8 and ableSineBK_Minus80toPlus80resZeroPointSix_Q8"" be right shif 8?

Thanks
