Abstract

Raindrops adhered to camera lens or windshield are inevitable in rainy scenes and can become an issue for many computer vision systems such as autonomous driving. Because raindrop appearance is affected by too many parameters, therefore it is unlikely to find an effective model based solution. Learning based methods are also problematic, because traditional learning method cannot properly model the complex appearance. Whereas deep learning method lacks sufficiently large and realistic training data. To solve it, in our work, we propose the first photo-realistic dataset of synthetic adherent raindrops for training. The rendering is physics based with consideration of the water dynamic, geometric and photometry. The dataset contains various types of rainy scenes and particularly the rainy driving scenes. Based on the modeling of raindrop imagery, we introduce a detection network which has the awareness of the raindrop refraction as well as its blurring. Based on that, we propose the removal network that can well recover the image structure. Rigorous experiments demonstrate the state-of-the-art performance of our proposed framework.

  • Hoa et al.'s proposed algorithm performed better than all other algorithms in terms of SSIM and PSNR scores.

    “The quantitative results showed that Hoa et al. proposed algorithm performed better than all other algorithms in terms of SSIM and PSNR scores.”

    From A Review of Detection and Removal of Raindrops in Automotive Vision Systems (2021) · cites this paper as [56]

    Section 5.1 reports that the complete model outperformed the compared methods on both PSNR and SSIM on the synthetic test set. The claim omits that setting: Section 5.2 says its quantitative results on the real-world dataset were on par with Qian’s method, not better than every comparator. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Hoa et al. developed a synthetic raindrop generator and used synthetically generated rainy scenes along with real rainy scenes to train their GAN-based raindrop removal algorithm.

    “Hoa et al. [56] tried to solve this problem by developing a synthetic raindrop generator and using the synthetically generated rainy scenes, along with real raindrop real rainy scenes to train their GAN-based raindrop removal algorithm.”

    From A Review of Detection and Removal of Raindrops in Automotive Vision Systems (2021) · cites this paper as [56]

    Section 3 describes generating photorealistic raindrops for a synthetic training dataset, and Section 5.2 describes training on a real-world raindrop dataset. But Section 4 describes the authors’ removal method as a three-subnetwork detection-and-reconstruction architecture, not a GAN; Section 2.2 attributes the GAN-based method to Qian et al. The paper also does not say the synthetic and real scenes were combined in one training set. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • When trained using Qian et al.'s dataset with only a rough mask, Hoa et al.'s proposed algorithm produced results on-par with Qian and better than all other methods.

    “Results showed that the proposed algorithm produced results that were on-par with Qian [49] and better than all other methods.”

    From A Review of Detection and Removal of Raindrops in Automotive Vision Systems (2021) · cites this paper as [56]

    Section 5.2 says the methods trained on Qian’s dataset using rough masks achieved quantitative results on par with Qian’s. The statement that the proposed method outperformed other methods appears in Section 5.1, but it concerns the complete model on a synthetic dataset, not the rough-mask model on Qian’s dataset. Page numbers are unavailable in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Hoa et al.'s proposed algorithm generated de-rained images with the least artifacts compared to other benchmarked methods.

    “The proposed algorithm as well generated de-rained images with the least artifacts, as compared to other methods benchmarked.”
  • Qualitatively, Hoa et al.'s proposed algorithm, as well as Qian's and DID-MDN, removed most raindrops successfully.

    “Qualitatively, the proposed algorithm, as well as Qian’s and the DIID-MDN removed most raindrops successfully.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
