Need: openCV 3.1，工程中需要根据路径include
支持420yuv格式的VR视频不同mapping之间的转换与计算spsnr
重构了代码结构，源代码只能gcc编译，建立了vs工程。为便于比较，master第一个commit直接是源代码，不能编译通过。加入了多种mapping以及支持rotate的操作 #Usage: 支持remap与comapre S-PSNR/L-PSNR两种操作 ##TAppRemap:
TAppRemap.exe [-i input] [-o output] [-f filter] [-m input_height] [-b input_width] [-n output_height]
[-v output_width] src dst [-c rotx -d roty -e rotz] [-k file.txt] [-g 1] [-u 1] [-j 10-8] [-s 150]
-i ... Input file type, common: rect eqar cube [rect]
***added:** aitoff, sanson, two(used for mapping) poletop, poledown(used to get the pole
of the top/down of rect) recttop_inv, rectdown_inv (used for inv)*
***not used:** dyad, mult, bmul, trec, brec, grid, beqr, teqr, merc, cos2*
-o ... Output file type: cube, rect, eqar, merc, view [rect]
-f ... Filter type: nearest, linear, bicubic, lanczos [mapping: lanczos, compare:bicubic]

-t ... Tracking data file [none]\n"
-y ... Blend data together (only works with orec, etc ...) [off]
-z ... Number of frames [MAX]

-e ... rotation of z-axis(-pi--pi) [0]
-k ... file describe rotation
-g ... is first frame rotate [0]
-u ... is inv rotate mapping [0]
-j ... ColorFormat(bits) [8-8]
-s ... skipFrameNum [0]
code中有两种坐标系，第一种是code base定义的 v1 ^ | >v2 | / |/---->v0
第二种是旋转矩阵所对应的
Y(y)

/---->Z(x)

###Example:
###Remap:
TappRemap.exe -i rect -o aitoff -m 2048 -b 4096 -n 1024 -v 2048 -z 10 input.yuv
aitoffOut_Rotate.yuv -c 0.8 -d 1.0 -g 1
TappRemap.exe -i rect -o cube -m 2048 -b 4096 -n 512 -v 512 -z 10 input.yuv cube.yuv
TappRemap.exe -i rect -o poledown -m 2048 -b 4096 -n 512 -v 512 -z 10 input.yuv poleOut.yuv
###Inv Remap:
TappRemap.exe -i aitoff -o rect -m 1024 -b 2048 -n 2048 -v 4096 -z 10 aitoffOut_Rotate.yuv
invRect.yuv -c 0.8 -d 1.0 -g 1 -u 1
TappRemap.exe -i poledown -o rectdown_inv -m 512 -b 512 -n 512 -v 4096 -z 10 poleOut.yuv rectInv.yuv
##TAppCompare: 支持不同投影方式、不同旋转角度的比较S-psnr或L-psnr或WS-PSNR
