Symmetrized Dot‐patterns (Sdp) of Irregular Compressive Stress‐strain Relationships 1

Symmetrized dot‐pattern displays (SDP) of the kind used in speech analysis and medical diagnosis can also be used to visualize textural differences between and among crunchy foods. Meaningful interpretation of the patterns in terms of textural characteristics, however, will require further study of two topics: how the display parameters, notably the number of points and symmetry axes affect the resulting image perception, and how factors such as the specimen's geometry and moisture content, for example, affect the pattern's morphological features.
