Main Methods:

• The proposed algorithm utilizes an energy optimization framework, modified to operate on patches instead of individual pixels.
• Nearest neighborhood searches are accelerated using a k-means clustering-based search tree.
• Principal Component Analysis (PCA) is employed to reduce the dimensionality of input vectors.

Main Results:

• The developed algorithm achieves high-quality perspective texture synthesis.
• The approach demonstrates significantly reduced computation time compared to existing similar methods.
