Cyber City Image in Shenyang (2025): Image Derivatives & Perception Survey

This collection accompanies a study of Cyber City Image (CCI) for six post-industrial heritage sites in Shenyang, China. It contains two restricted-access datasets: (A) numeric derivatives from semantic segmentation of online city images (per-image pixel-share features for 20 ADE20K classes and seven computed indicators including SFI, VII, AIH, OSI, GVI, SVI, SEI), and (B) an image-based perception survey (IHMA) with 25,000 ratings (0–100) of attractiveness/willingness-to-visit and nine perceived attributes later aggregated into five perception dimensions (Vitality, Sense, Fit, Control, Access).
