Image Preprocessing in Container Identifier Recognition System Using Multiple Threshold Regions

Preprocessing and Recognition of Characters in Container Codes

This paper describes the recognition of container code characters. The system has to deal with outdoor images which usually have damaged characters and obtain an answer in real time. Tophat transformation, equalization and adaptive cropping have been applied so as to reduce the noise and correct the inclusion box. The training corpus is artificially grown by applying controlled deformations of ...

Improving Eigenface Face Recognition by using Image Registration Preprocessing Methods

This paper investigates using image registration through spatial transformation to incrementally improve eigenface detection in training sets containing non-centered head orientation. In identifying a new face, a training set of faces is created from a scene. After face detection in an image, these faces may exhibit different head orientations. The use of several images combined through image r...

Image preprocessing for optical character recognition using neural networks

Primary task of this master’s thesis is to create a theoretical and practical basis of preprocessing of printed text for optical character recognition using forward-feed neural networks. Demonstration application was created and its parameters were set according to results of realized experiments. Project definition and task determination 1. Write a introduction about the problematics of optica...

Image preprocessing for CBIR system

This article describes the way in which image is prepared for content-based image retrieval system. Our CBIR system is dedicated to support estate agents. In our database there are images of houses and bungalows. All efforts have been put into extracting elements from an image and finding their characteristic features in the unsupervised way. Hence, the paper presents segmentation algorithm bas...
