The present disclosure attempts to evaluate how the texture of an object is perceived based on visual features of the topological skeleton of the object. A camera Sobtains a color image by taking an image of an object, which serves as an evaluation target. Within the image obtained, a visual feature area, which is likely to strike a person's eye when the person claps his/her eyes on the object, and an intensity of a visual stimulus of each pixel of the visual feature area are extracted. Visual skeleton features of each pixel of the image are determined within a contour region which is composed of the visual feature areas extracted. The visual skeleton features determined are shown on a display.

Texture evaluation system

The disclosure describes plastic formed products comprising: one selected from the group consisting of a thermoplastic resin and a thermosetting resin; and 0.1 to 10 wt % of at least one selected from the group consisting of ferric oxide hydroxide particles, hematite particles, magnetite particles and maghemite particles; wherein (1) the average major axial diameter or the plate diameter of said ferric oxide hydroxide particles is 0.02 or 2.0 .mu.m and the average aspect ratio or the plate ratio thereof is 2 to 20, (2) the average particle size of said hematite particles, magnetite particles and maghemite particles is 0.01 to 1.0, the BET specific surface area thereof is 1 to 120 m.sup.2 /g and the water content on the surfaces thereof is not less than 0.02 wt %/m.sup.2 /g.
