Accuracy Improvement from PIM Technology Breakthrough
One of the core innovations of CanonSwap is the Partial Identity Modulation (PIM) module, a technology that enables millimeter-accuracy control of facial modifications.PIM generates spatial masks that target only key facial feature areas such as the eyes, nose, and mouth, ensuring that non-facial areas such as the hair and the background are completely unaffected.
At the technical realization level, the PIM module contains three key components: an attention mechanism to determine the modification region, a lightweight neural network to handle feature fusion, and residual connectivity to keep the non-targeted region intact. Experimental data shows that the use of PIM technology can reduce the facial feature point alignment error to within 0.3 pixels, which improves the accuracy by 8 times compared to traditional methods such as DeepFaceLab, and at the same time reduces the edge artifacts by 751 TP3 T. This technological breakthrough is the key to CanonSwap's ability to achieve movie and TV-grade face-swap quality.
