In a wavelet transform section, wavelet-transform coefficient signals are obtained by two-dimensional wavelet transformation, employing a low-pass filter which has a characteristic that its response at a frequency greater than a spatial frequency corresponding to grid pitch is approximately zero. Based on the direction of the grid judged by a direction judging section, a suppressing section applies one-dimensional wavelet transformation to a signal containing a grid component (when a vertical grid is used, signal HL1), in the grid direction. Then, a low frequency transform coefficient signal of the transform coefficient signals is made zero. The signal, made zero, and the remaining signals, are subjected to inverse one-dimensional wavelet transformation. In an inverse wavelet transform section, the original image is restored with a signal having a suppressed grid component.

Unique transparent polypropylene articles that can be tailored to become opaque when exposed to a sufficiently high temperature and which returns to substantially the same transparency level upon cooling. Such formulations include non-polypropylene polymeric constituents that exhibit refractive index measurements similar to the base clarified polypropylene at lower temperatures, as well as melting temperatures well below that for the base clarified polypropylene.

In particular, the non-polypropylene polymeric constituents should exhibit melting temperatures well below that for the base clarified polypropylene, from about 60 to about 100° C. (well below the typical polypropylene melting temperatures of roughly about 160-190° C. for homopolymer and about 140-170° C. for typical random copolymer, both nucleated or non-nucleated). In this manner, a temperature sensitivity measuring thermoplastic article may be provided, and may be tailored to specific temperature ranges dependent on the melting temperatures exhibited by the non-polypropylene polymeric constituents. Methods of measuring temperature levels via the transformation of transparent polypropylene formulations to at least partially opaque versions thereof are also encompassed within this invention.
