From ba994f4404b6eadcab4e0ead46ef4d3ffeceb024 Mon Sep 17 00:00:00 2001 From: Antoine Villeret Date: Thu, 10 Jul 2014 14:39:22 +0000 Subject: lots of changes ! 1. switch to a new build system based on automake (because we need to check for some lib on ./configure before make) 2. sort files in different directory 3. add some new features (some of them need OpenCV >= 2.4.5) svn path=/trunk/externals/pix_opencv/; revision=17324 --- pix_opencv_warpperspective-help.pd | 119 ------------------------------------- 1 file changed, 119 deletions(-) delete mode 100644 pix_opencv_warpperspective-help.pd (limited to 'pix_opencv_warpperspective-help.pd') diff --git a/pix_opencv_warpperspective-help.pd b/pix_opencv_warpperspective-help.pd deleted file mode 100644 index 4c8749b..0000000 --- a/pix_opencv_warpperspective-help.pd +++ /dev/null @@ -1,119 +0,0 @@ -#N canvas 616 396 980 660 10; -#X obj 24 25 gemhead; -#X obj 411 543 gemwin; -#X msg 411 509 create \, 1; -#X msg 492 509 destroy; -#X obj 24 565 pix_texture; -#X obj 203 571 print; -#X obj 24 591 rectangle 4 3; -#X obj 24 4 tgl 15 0 empty empty empty 17 7 0 10 -262144 -1 -1 0 1 -; -#X obj 24 539 pix_opencv_warpperspective; -#X msg 76 367 mapMatrix 1 0 0 0 1 0 0 0 1; -#X text 75 348 you can also set the map matrix directly; -#X msg 76 387 mapMatrix 0.5 0 0 0 0.5 0 0 0 1; -#X text 281 366 identity; -#X text 302 388 scale by 0.5; -#X msg 76 407 mapMatrix 0 1 0 1 0 0 0 0 2; -#X text 275 409 rotation by 90deg and scale by 0.5; -#X obj 24 93 pix_video; -#X obj 24 133 pix_flip; -#N canvas 1 105 936 545 wrap_perspective_GPU 0; -#X obj 251 443 mesh_square 10 10; -#X obj 301 277 /; -#X obj 351 278 /; -#X obj 301 233 loadbang; -#X obj 251 356 GEMglMultTransposeMatrixf; -#X obj 251 414 translateXYZ 1 1 0; -#X obj 251 299 scaleXYZ 0.003 0.003 0; -#X obj 251 376 scaleXYZ 639 479 0; -#X obj 251 212 translateXYZ -5.33333 -4 0; -#X obj 251 395 scaleXYZ 0.5 0.5 0; -#X msg 301 255 5.3333 320; -#X msg 377 255 4 240; -#X msg 423 330 \$1 \$4 0 \$7 \$2 \$5 0 \$8 0 0 1 0 \$3 \$6 0 \$9; -#X text 46 22 wrap_persective can be easilly computed by the GPU in -order to boost performace; -#X obj 251 188 spigot; -#X obj 290 138 tgl 15 0 empty empty empty 17 7 0 10 -262144 -1 -1 0 -1; -#X obj 39 105 t a a; -#X obj 39 190 spigot 1; -#X obj 92 164 == 0; -#X obj 39 253 rectangle 4 3; -#X obj 39 233 pix_texture; -#X obj 39 211 pix_opencv_warpperspective; -#X text 306 137 switch CPU / GPU; -#X text 454 256 Since the matrice is computed for somthing that range -from 0 to 639 in X \, and from 0 to 479 in Y \, one have to convert -(scale / translate) the primitive coordinate to fit the transformation -matrix.; -#X obj 41 62 inlet; -#X connect 1 0 6 1; -#X connect 2 0 6 2; -#X connect 3 0 10 0; -#X connect 3 0 11 0; -#X connect 4 0 7 0; -#X connect 5 0 0 0; -#X connect 6 0 4 0; -#X connect 7 0 9 0; -#X connect 8 0 6 0; -#X connect 9 0 5 0; -#X connect 10 0 1 0; -#X connect 11 0 2 0; -#X connect 12 0 4 1; -#X connect 14 0 8 0; -#X connect 15 0 14 1; -#X connect 15 0 18 0; -#X connect 16 0 17 0; -#X connect 16 1 14 0; -#X connect 17 0 21 0; -#X connect 18 0 17 1; -#X connect 20 0 19 0; -#X connect 21 0 20 0; -#X connect 21 1 12 0; -#X connect 24 0 16 0; -#X restore 161 604 pd wrap_perspective_GPU; -#X msg 43 233 dstMatrix 0 0 0 1 1 1 1 0; -#X msg 59 281 srcMatrix 0 0 0 1 1 1 1 0; -#X text 203 234 destination matrix; -#X text 103 261 source matrix; -#X text 229 279 the same as dst lead to identity map matrix; -#X msg 71 306 srcMatrix 1 0 1 1 2 1 2 0; -#X text 234 299 translation also lead to identity map matrix while -translation is not a perspective transformation; -#X text 126 327 TODO more src examples...; -#X text 112 88 pix_opencv_warpperspective computes the perspective -transformation between dstMatrix and srcMatrix and corrects the image -image according to this perspective transformation; -#X text 111 129 the trasnsformation matrix is also sent through the -right outlet to be applied in OpenGL for example; -#X text 114 159 the transformation matrix could also be set by mapMatrix -message to apply the transformation; -#X text 112 25 see examples/05-perspective_correction for an example -of the use of pix_opencv_warpperspective with pix_opencv_findchessboardcorners -to correct perspective; -#X obj 24 112 pix_grey; -#X msg 123 480 invert \$1; -#X obj 123 452 tgl 15 0 empty empty empty 17 7 0 10 -262144 -1 -1 0 -1; -#X text 140 450 invert transformation matrix (same as swaping src and -dst matrix); -#X connect 0 0 16 0; -#X connect 2 0 1 0; -#X connect 3 0 1 0; -#X connect 4 0 6 0; -#X connect 7 0 0 0; -#X connect 8 0 4 0; -#X connect 8 1 5 0; -#X connect 9 0 8 0; -#X connect 11 0 8 0; -#X connect 14 0 8 0; -#X connect 16 0 31 0; -#X connect 17 0 8 0; -#X connect 19 0 8 0; -#X connect 20 0 8 0; -#X connect 24 0 8 0; -#X connect 31 0 17 0; -#X connect 32 0 8 0; -#X connect 33 0 32 0; -- cgit v1.2.1
