The overall architecture of IDESplat. IDESplat is composed of three key parts: a feature extraction backbone, an iterative depth
probability estimation process, and a Gaussian Focused Module (GFM). The iterative process consists of cascaded Depth Probability
Boosting Units (DPBUs). Each unit combines multi-level warp results in a multiplicative manner to mitigate the inherent instability of a
single warp. As IDESplat iteratively updates the depth candidates and boosts the probability estimates, the depth map becomes more precise,
leading to accurate Gaussian means.
