The statement concerns what was presented in the Mono-SLAM benchmark study: whether deep learning SLAM methods like DROID-SLAM are robust to camera shake but perform poorly in featureless environments. First, consider the concept: camera shake introduces motion blur and viewpoint changes that can challenge correspondence and pose estimation; robust SLAM methods aim to handle such disturbances by leveraging strong feature tracking, motion models, or learned priors. Deep learning SLAM approaches such as DROID-SLAM rely on dense optical flow and learned representations to propagate information across frames, which can help maintain pose estimates when the camera experiences shake because they can model context and avoid relying solely on short-term geometric cues. This supports the part of the statement claiming robustness to camera shake.

On the other hand, featureless environments (e.g., textureless walls, repetitive patterns) reduce the distinct visual cues available for matching or triangulation. Many SLAM systems, including learned ones, can struggle here because without distinctive features the network may have difficulty disambiguating correspondences, resulting in drift or failure. Therefore, the claim that deep learning SLAM methods may do badly in featureless environments is plausible and aligns with common challenges in SLAM research where textureless scenes degrade localization accuracy.

However, there are important caveats: results depend on dataset, specific architecture, training regime, and evaluation metrics. Some DL-based SLAM methods incorporate priors or multi-frame redundancy that can mitigate featureless issues to some extent, and robustness to camera shake can also vary with motion patterns, exposure, and sensor noise. Thus, the overall assessment from a Mono-SLAM benchmark study would reflect a particular setup and may not generalize universally to all DL-SLAM systems or all featureless scenarios. The takeaway is that the statement captures commonly observed strengths and weaknesses of such methods, while acknowledging that real-world performance is nuanced and dataset-dependent.
