Script Identification Based on Morphological Reconstruction in Document Images

Scripts and Numerals Identification From Printed Multilingual Document Images

“…The feature extractor consists of two stages. Dhandra et al [6] [7] are continuation of paper [8] demonstrates the feasibility of morphological reconstruction approach for script identification at word level.…”

“…It examines the use of discriminating features (aspect ratio, strokes, eccentricity, etc,). Dhandra et al [8]developed a system that includes a feature extractor using morphological operation and a classifier. The feature extractor consists of two stages.…”

“…In the work of Joshi et al [14], different Indian scripts are identified with a Log Gabor filter. Regarding token based approach Judith Hochberg et al [8], [9] exemplars are grouped into clusters based on a similarity measure. A representative template is then extracted from each cluster to identify those characters.…”

Dimension Reduction for Script Classification - Printed Indian Documents

“…B Patil and Subbareddy [4] have proposed a neural network based system for script identification of Kannada, Hindi and English languages. Dhandra et al, [5] have exploited the use of discriminating features (aspect ratio, strokes, eccentricity, etc,) as a tool for determining the script at word level in a bi-lingual document containing Kannada, Tamil and Devnagari containing English numerals. A method to automatically separate text lines of Roman, Devanagari and Telugu scripts has been proposed by Pal et al, [6].…”

Density Based Script Identification of a Multilingual Document Image

“…Many techniques have been proposed to identify various scripts. In recent advances, the scripts are identified using morphological reconstruction & hole filling [8], water reservoir techniques [9], projection profiles [10], moments & run-length histogram [3], top & bottom profiles [11] [12], vertical & horizontal profiles [13], steerable pyramid features [14], texture features [15] & wavelet energy histogram. Entropy or energy evaluation has been done in a multilingual document image wherein column entropies are considered for the purpose of identification [16].…”
