Error with cv.warpAffine

[chengchunhsu]

Hi, when I try to parse a new image with code on github page

load data/paperdoll_pipeline.mat config;
input_image = imread('/path/to/new_image.jpg');
input_sample = struct('image', imencode(input_image, 'jpg'));
result = feature_calculator.apply(config, input_sample)

I get this message from matlab:

[28-Jan-2018 03:19:28] Error:feature_calculator: 1 / 1
Error using cv.warpAffine
Attempt to execute SCRIPT warpAffine as a function:

result =

I've tried to clone mexopencv 2.4.11 from lastest branch again, but it doesn't help... would you give me any possible solution so I can check?

I am using Matlab R2017b on Ubuntu 17.10 with OpenCV 2.4.11 thank you!

@chengchunhsu The error indicates mexopencv fails to compile. I would recommend you completely replace the mexopencv package with the latest version. Make sure to compile and see if that succeeds first.

@kyamagu Thanks! after i update mexopencv to the lastest version (with OpenCV 3.3.1) it works fine now.

btw in the middle i fixed "libopencv_imgproc.so.3.3 not found" problem with solution here: https://github.com/GaoHongchen/DIPDemoQt5/issues/1#issuecomment-284103343 post it here in case anyone need.
