In the field of image generation, particularly in the creation of panoramic images, utilizing large pre-trained text-to-image (T2I) models for multi-view image generation is becoming a trend. However, due to the high cost of obtaining multi-view images, many researchers are seeking methods that do not require fine-tuning. Some current methods on the market either can only handle simple correspondences or require extensive fine-tuning to capture complex correspondences.

Recently, researchers have proposed a new method — PanoFree. This is an innovative multi-view image generation technique that does not require fine-tuning and supports the generation of long images, 360-degree images, skybox images, and other multi-view panoramic images.
Generating Long Images:
360° Panoramic Generation:
VR Panoramic Images:
PanoFree generates multi-view images through an iterative deformation and patching process, addressing common issues of consistency and artifacts caused by error accumulation without any fine-tuning.
PanoFree's approach enhances cross-view awareness and improves the deformation and patching process through various techniques, including cross-view guidance, risk area estimation and erasing, and symmetric bidirectional guidance for loop generation.
Additionally, PanoFree utilizes guided semantic and density control to preserve scene structure. In experiments with flat, 360-degree, and global panoramic images, PanoFree demonstrated significant error reduction, improved global consistency, and significantly enhanced image quality without additional fine-tuning.
Compared to existing methods, PanoFree improves time efficiency by 5 times, GPU memory usage efficiency by 3 times, and the diversity of results in user studies by 2 times.
Overall, PanoFree provides a viable alternative for researchers who wish to reduce costs, avoid tedious fine-tuning, or use additional pre-trained models.
