Instance-Level Image Translation With a Local Discriminator

Blog Article

Instance-level image translation aims to only translate instance of interest and can be operated more finely and flexibly than object-level and holistic-level image translation.However, current algorithms are not suitable to do it since they employ a holistic or object level’s discriminator that tends to Playing Cards change the whole image or all instances.To address the issue, we propose a simple yet effective local discriminator, in which the input image is split into two parts, region of interest (ROI) and background.Instance mask is employed to align the Tote Bag ROI and the background is design to be random in a prior distribution to mitigate a divergence between the ROI and the background.In this way, we obtain translated instance with decent margins without artifacts as current algorithms get.

Moreover we propose a new architecture to simultaneously realize versatile instance-level image translation.Experimental results prove that our proposed algorithm outperforms the state-of-the-art in position accuracy and background retainment by a clear margin.
