This paper proposes DiffusionInst, a novel framework that represents instances as instance-aware filters and formulates instance segmentation as a noise-to-filter denoising process. The model is trained to reverse the noisy groundtruth without any inductive bias from RPN. During inference, it takes ...

DiffusionInst is the first work of diffusion model for instance segmentation.We hope our work could serve as a simple yet effective baseline, which could inspire designing more efficient diffusion frameworks for challenging discriminative tasks.
DMs最早可以追溯到由Sohl-Dickstein等人[8]提出的扩散概率模型(Diffusion Probabilistic Model, DPM),但受到当时硬件条件的限制,该方法没能得到广泛的运用。扩散模型涉及两个互关联的过程,分别是前向过程与反向过程。前向过程将数据分布转换为更简单的先验分布,例如高斯分布;相对应的反向过程,利用经过训练的神经网络,...
By utilizing the information between different stages of step sizes, the accuracy of the segmentation model can be improved. This research on instance segmentation tasks is valuable. The paper conducts performance tests on instance segmentation models on the COCO and LVIS datasets and compares the ...
Any threshold model has a threshold or a set of thresholds that are used to distinguish a range of values for the behavior predicted by the model. One of the most frequently used models among the threshold models is the Linear threshold model (LTM). In LTM, each edge e=(u,v)∈E has...
