Grandes quantidades de documentos impressos em cores são publicadas todos os dias. Algumas abordagens de OCR de imagens de documentos impressos em cores são fornecidas, mas normalmente não funcionarão se as imagens de entrada estiverem distorcidas. Nos últimos anos, muitos algoritmos foram fornecidos para detectar a distorção de imagens de documentos monocromáticos, mas nenhum deles processou imagens de documentos impressos em cores. Todos esses métodos pressupõem que o texto é impresso em preto sobre fundo branco e não pode ser aplicado para detectar distorções em imagens de documentos impressos em cores. Neste artigo, propomos um algoritmo para detectar o ângulo de inclinação de uma imagem de documento impresso em cores e reconstruí-lo. Nossa abordagem primeiro determina a variação da contagem de transições de cores em cada ângulo (de -45

Abstract: Large amounts of color-printed documents are published now everyday. Some OCR approaches of color-printed document images are provided, but they cannot normally work if the input images skew. In the past years, many algorithms are provided to detect the skew of monochrome document images but none of them process color-printed document images. All of these methods assume that text is printed in black on a white background and cannot be applied to detect skew in color-printed document images. In this paper, we propose an algorithm to detect the skew angle of a color-printed document image and reconstruct it. Our approach first determines variation of color-transition count at each angle (from -45
