Effects of outline shape in object recognition
The use of outline shape in recognizing objects was investigated in four experiments. In Experiment 1, subjects matched a shaded image to either another shaded image or a silhouette. In Experiment 2, subjects initially named shaded images; later they named either shaded images or silhouettes. Performance in both experiments was predicted by changes in the outline shape of the stimuli. The same ...
متن کاملRelation Between RNA Sequences, Structures, and Shapes via Variation Networks
Background: RNA plays key role in many aspects of biological processes and its tertiary structure is critical for its biological function. RNA secondary structure represents various significant portions of RNA tertiary structure. Since the biological function of RNA is concluded indirectly from its primary structure, it would be important to analyze the relations between the RNA sequences and t...
متن کاملAnalysis of foot shape variation based on the medial axis of foot outline.
The variations in foot outline forms are analyzed by using flexion angles of the medial axis of foot outline. Foot outline and 12 conventional measurements taken on the right foot of 443 male and 297 female subjects with no visible pathological deformation of the foot were used for analyses. The results indicate that the foot is outflared in most of the subjects. Medial bulge and lateral concav...
متن کاملA New Approach of Outline Shape Matching
We present in this paper a contribution to use the knowledge in the matching problem. A solution is given for the knowledge modeling. The 3D objects of free form are modeled from their different silhouettes. To any silhouette is associated one descriptor written following the specific language noted LWDOS (Language for Writing Descriptors of Outline Shapes). This representation of knowledge is ...
متن کاملEthnical Variation of Head Shapes in Fars and Turkman Young Men (17-20 Year-Old)
Purpose: This study was done for determining of head dimensions and head shapes. The purpose of the present study was to determine head dimensions and shapes. Materials and Methods: This discriptive and cross sectional study was conducted on normal 17-20 year-old native Fars and Turkman ethnic groups in Gorgan. Martin saler scalope was used to measure cephalic length and width, then cephalic i...
