TEMPERATURE SENSE ESTIMATION DEVICE, TEMPERATURE SENSE ESTIMATION METHOD, AND PROGRAM

摘要

The present invention estimates an evaluation value of temperature sense closer to human perception. An image feature amount extraction unit (11) extracts an image feature amount from an input image. A temperature sense estimation unit (12) estimates a temperature sense score from the image feature amount using a temperature sense estimation model that has learned in advance the correlation between image feature amounts and temperature sense scores. The temperature sense score may be weighted using a material weight preset for material information corresponding to the input image. The image feature amount may comprise a representative value of coordinates a*, b* in a Lab three-dimensional space, or a color histogram obtained by dividing the Lab three-dimensional space into a predetermined number.
