| Based on https://github.com/fabiotosi92/ZipDepth - Converted to CoreML for use on iPhone Devices, Internal testing suggested iPhone 12> will attain good results | |
| ๐ Quantitative Results | |
| ZipDepth achieves state-of-the-art accuracy among lightweight embedded models on NYUv2, KITTI, ETH3D, ScanNet, and DIODE, while being significantly more efficient than large pretrained models. | |

| ๐๏ธ Architecture | |
|  | |
| The encoder is organized in four hierarchical stages. Stages 1โ2 use RepVGG reparameterizable blocks (3ร3 + 1ร1 + identity branches fused into a single 3ร3 at inference) augmented with Strip Pooling Attention for horizontal/vertical context. Stage 3 adds Squeeze-and-Excitation channel attention and a Global Context Block. Stage 4 deepens the representation with additional RepVGG blocks. | |
| The neck combines SPPF multi-scale pooling with a Cross-Scale Fusion module. The decoder is a lightweight FPN with a Convex Upsampling head for sub-pixel-accurate depth maps. | |
