Object Feature Extraction of Songket Image Using Chain Code Algorithm

Abstract

The study was aimed at determining the feature of a motif found in a Songket image in order to make the object detectable and readable. The method used was image color segmentation in the form of a process of segmentation of the image area based on the similarity in colors, which was continued with the binary process that aims to change the image into binary form (0 and 1), so that it only has two colors namely black and white. This study also used mathematical morphology in detecting objects, by using dilation operation and filling holes. After the process of mathematical morphology was completed, the next process was motif extraction by applying moore contour tracking algorithms and the development of chain code algorithms. The results of the process carried out showed that the development chain code algorithm can generate the number of objects, the length of chain code, and probable value of rate of appearances of each chain code in a motif, despite there are some objects in a motif. Then the values are stored into the database as The Feature of Songket Motifs.

Review on Local Binary Patterns Variants as Texture Descriptors for Copy-Move Forgery Detection

“…Feature extraction aims to compute the specific representation of the data that can highlight relevant information [1]. Besides, it is a useful tool for removing irrelevant or redundant information and reducing feature dimensionality [16]. LBP variants are methods under the group of binary descriptors for extracting image features by describing the spatial structure of the gray image texture.…”
