no code implementations5 Jul 2017 Mojtaba Masoudi, Hamid-Reza Pourreza, Mahdi Saadatmand Tarzjan, Fateme Shafiee Zargar, Masoud Pezeshki Rad, Noushin Eftekhari

Todays, researchers in the field of Pulmonary Embolism (PE) analysis need to use a publicly available dataset to assess and compare their methods.

Parallel Stroked Multi Line: a model-based method for compressing large fingerprint databases

no code implementations10 Jan 2016 Hamid Mansouri, Hamid-Reza Pourreza

At high compression rates, according to PSNR values, mean EER rate and visual quality, the encoded images with JPEG2K can not be identified from each other after compression.

Towards the Application of Linear Programming Methods For Multi-Camera Pose Estimation

no code implementations8 Dec 2015 Masoud Aghamohamadian-Sharbaf, Ahmadreza Heravi, Hamid-Reza Pourreza

We presented a separation based optimization algorithm which, rather than optimization the entire variables altogether, This would allow us to employ: 1) a class of nonlinear functions with three variables and 2) a convex quadratic multivariable polynomial, for minimization of reprojection error.
