It floats on the surface by causing a dent on it. Imagine gently placing a ping-pong ball on the surface of a pond. Takahashi, who was part of the study, says that may help scientists "detect the primordial gravitational waves generated at the beginning of the universe and approach the mystery of the origin of the universe." What is a gravitational wave? "We are trying to clarify how supermassive black holes formed in the universe," says Keitaro Takahashi at Kumamoto University in Japan. Hundreds of scientists have tuned into this field of study in recent years because black holes and gravitational waves could be a key to unlock the universe's biggest secrets, including invisible dark matter.
254–269.In June 2023, scientists announced they had found evidence to suggest that the universe is replete with a "cosmic symphony" of massive gravitational waves caused by pairs of black holes spinning around each other in a very slow dance.

Moreover, the extension of our method towards the rainy image segmentation and detection tasks validates the practicality of the proposed method in outdoor applications.Ĭlean background preservation occluded region filtering raindrop and raindrop-free images raindrop detection and removal shape adaptive network. Extensive experiments on synthetic and real-world datasets demonstrate that the proposed method achieves significant improvements over the recent state-of-the-art raindrop removal methods. Second, a two-branch Multi-scale Shape Adaptive Network (MSANet) is proposed to detect and remove diverse raindrops, effectively filtering the occluded raindrop regions and keeping the clean background well-preserved. First, we establish a large-scale dataset named RaindropCityscapes, which includes 11,583 pairs of raindrop and raindrop-free images, covering a wide variety of raindrops and background scenarios. In this paper, we address these raindrop removal problems from two perspectives. Second, recent deraining methods tend to apply shape-invariant filters to cope with diverse rainy images and fail to remove raindrops that are especially varied in shape and scale. First, publicly available raindrop image datasets have limited capacity in terms of modeling raindrop characteristics (e.g., raindrop collision and fusion) in real-world scenes. Previous explorations have mainly been limited in two ways. Removing raindrops from a single image is a challenging problem due to the complex changes in shape, scale, and transparency among raindrops.
