  • In order to establish an effective index system of streetscape visual evaluation, 6 quantitative indices were proposed to reflect the objective visual attributes of streetscape based on the idea of image processing, and their validity was verified by digital images of 10 walking streets. The mathematical analyses of subjective and objective indices show that street width-to-height ratio, street width, sky openness index, visual entropy, and color complexity can reflect the streetscape's objective visual attributes effectively (correlation coefficient is above 0.633, significance is smaller than 0.05); the complexity of sight is the most important factor in the streetscape visual evaluation because of its high weight of 22.6%.
