Published Online: Pattern Similarity Score Based on One Dimensional Time-series Analysis
JPRR Article #744
Pattern recognition and matching operation includes parameters such as mean, correlation, mutual information etc. A novel procedure to quantify similarity in different images based on time-series analysis is reported here. The proposed technique consists of orderly application of various mathematical transformations on one dimensional time series obtained from a 2d-image array. These transformations include array to time-series conversion, local maxima detection-joining, and calculation of cumulative angle. The final calculated parameter is a direct pointer to the image similarity. The proposed technique has performed well against traditional image comparison techniques under specific circumstances. The technique can be also used to identify similar patterns in a single image. The simulation codes have been written on SCILAB platform.

Application of Approximate Equality for Reduction of Feature Vector Dimension 26-40
Reduction of feature vector dimension is a problem of selecting the most informative features from an information system. Using rough set theory we can reduce the feature vector dimension when all the attribute values are crisp or discrete.

Boosting Shape Classifiers Accuracy by Considering the Inverse Shape 41-54
Many techniques exist for describing shapes. These techniques almost exclusively consider the contour or the inside of the shape; the major problem for describing the outside of a shape, or inverse shape, being that it has an infinite extension.

Extending the K-Means Clustering Algorithm to Improve the Compactness of the Clusters 61-73
Clustering is a popular method essentially applied to data analysis, data mining, vector quantization and data compression. The most widely used clustering algorithm, which belongs to the group of partitioning algorithms, is the k-means.
