Paper Link: https://arxiv.org/pdf/2303.07428.pdf
TransNetR is an encoder decoder network which can be used for efficient biomedical image segmentation for both in-distribution and out-of-distribution datasets.

Table 1: Quantitative results on the Kvasir-SEG test dataset. The parameters are in Mil- lions and Flops are in GMac.
Figure 4: Cross-data result when models trained on Kvasir-SEG & tested on BKAI-IGH.LeakyReLU activation function. Finally, the output from the LeakyReLU is passed througha residual block which acts as the output of the residual transformer block.
Figure 5: Center-wise example images from the PolypGen dataset. Here, the variabilityamong the dataset from different centers can be observed. There is a differencein image resolutions and sizes, shapes, colors, textures and appearances and col-lection protocols.Figure 6: Qualitative result when the TransNetR is trained on Kvasir-SEG and tested on(a) PolypGen (center 6 (C6)) and (b) PolypGen (center 1 (C1)).13
