Abstract
The objective of this proposed work is to recognize the real time small indoor objects from the any scene or image of our working environment for visually impaired. This will be efficiently detect and recognize the indoor objects. The objects are detected and segmented automatically by exploiting the geometrical properties of the image regions. Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) and Combined DCT-DWT are implemented and evaluated for extracting features from the segmented object. In the Training phase, more than hundred objects were used for each category of the objects and dimension reduction of the features has been done for better result. The performance of the object recognition for visually impaired is evaluated along with the corresponding feature selection methods. The performance of the recognition system gives the recognition rate of 94. 44% with the usage of Combined DCT – DWT.
