 Developping models which can run on **limited resources** is one of the challenges in the medical field to guarantee **health equity**.
 Those **lightweight** models usually try to work on a reduced number of parameters and computation complexity. For the segmentation task however, 
-the existing methods produce results with lower quality than their non-lightweight counterparts due to the a lower representation capacity.

 There is therefore a need to develop lightweight models which also improve the segmentation quality.
