While traditional image magnification techniques such as bicubic interpolation simply copy pixels, Image Upscaler's AI algorithm establishes a complete detail reconstruction mechanism. Its technology kernel is trained with millions of high-definition images, enabling the CNN network to intelligently predict the texture details that should be in the zoomed-in area, realizing true super-resolution reconstruction.
In the processing flow, the system analyzes visual elements such as edge characteristics and color gradient of the image, and establishes differentiated processing strategies for different types of visual information. For example, it adopts the algorithm of sharpening edges for text areas, and focuses on keeping the color transition smooth for natural landscapes. This kind of adaptive processing makes the document still readable after 4x magnification, and the landscape photo maintains the natural look and feel.
Actual tests show that when processing images below 300 dpi, the AI method improves an average of 52% in PSNR (Peak Signal-to-Noise Ratio) metrics compared to the traditional method. especially in images containing key elements such as text, faces, etc., the improvement in detail reproduction is even more significant, which explains why this feature has become the preferred tool for photographers and designers.
