If the parameter values are correct the operatormedian_imagereturns the value2(H_MSG_TRUE) . The behavior in case of empty input (no input images available) is set via the operatorset_system('no_object_result',<Result>). If necessary, an exception is raised. ...

LULU filters are nonlinear rank selector operators which are computationally more competent and the performance of the operator is straightforward to describe. The comparison between Median and LULU filters, in this paper, is performed using two different image quality metrics which are RMSE and PSNR...

Median filtering is a popular nonlinear denoising operator, it not only can be used for image enhancement, and it also is an effective tool in application of anti-forensics. So, the blind detection of median filtering is a particularly hot topic. Different from the existing median filtering ...

A new rank order operator—the variable median filter—for the restoration of images corrupted with spike noise is introduced. It can be adapted to the diameter of noise grains, while all other useful properties of the 2-dimensional median filter—edge preservation and impulse noise attenuation—...
