Object-centric learning (OCL) aims to represent each object's information independently and minimize interference from backgrounds and other objects. OCL is expected to aid model generalization, especially in out-of-distribution (OOD) settings. However, the community's effort has been focused on improving unsupervised entity segmentation performances which is secondary to the main objective. We challenge this. We argue that segmentation is no longer the main barrier: recent class-agnostic segmentation methods reliably localize objects in a zero-shot manner. Instead, we advocate for a renewed emphasis on how decomposed representations can improve OOD generalization. As a first step, we propose Object-Centric Classification with Applied Masks (OCCAM) that exploits discovered objects to extract their representations for downstream classification tasks. Our experiments on datasets with background spurious correlations suggest that even in this task OCL representations do not lead to better generalization than object-centric representations provided by foundational segmentation models. These results showcase the importance of recognizing advances in zero-shot image segmentation when high-performant object-centric representations are the end goal. In addition to that, we suggest exploring new benchmarks for OCL methods evaluation that better reflect the problems these methods are designed to solve and highlight scenarios where OCL methods are more favorable solutions than foundational segmentation models.
