In Indian language, recognition of curved and multi-oriented text is difficult. In curved text, the shirorekha is curved and character will be at any rotated position. Also in case of multi-oriented text, the text is skewed at some angle. These issues make the recognition of this type of text complex [1][2]. In this paper, we propose envelope point approach for mode detection and direction of shirorekha (headline) of curved and multi-oriented text and removal of shirorekha of curved and straight text without any skew correction. This approach will be able to solve the recognition problem in orientations and multi-skew. Unlike water reservoir principle[1][2], the proposed approach detects direction of shirorekha by calculating the envelope point[2] for left, right, top and bottom side of the text and for removal of shirorekha, the relation is formed by filling the gap within and in between the characters.
