Malayalam has remarkably distinct lateral variations as compared to many other Indian languages with a number of curls and twists in the characters. Another very Figure 1: Malayalam Vowel Signs Figure 3: Segmentation Logic Flow Chart sequence of appearance in the word. The logic used to reduced the search subspace is that the first level search subspace has vowels, consonants, left vowel signs and conjuncts. The first recognized character/ sub character of a word falls into one of these four categories only. The search space further reduces for finding the subsequent character or sub character as independent vowels can appear only in the beginning of a word. The logic used behind the choice of search space for the classifier is based on the sequence of arrangement of the segments of the character. This logic facilitates accurate segmentation. RECOGNITION RATE OF DIFFERENT TYPES OF MALAYALAM CHARACTERS BASED ON THE PROPOSED METHODS Confusion characters usually misclassify in classical approaches. It is thus appropriate to compare the proposed approaches on their performances in classifying such similar characters. It is fascinating to see that the frequency capture approach yields better results with good discrimination between similar characters. Fe oe ae TABLEI.
