In this work, we propose a tool to scan a document-image acquired with a cameraphone. Firstly, we try to reduce the noise in the document-image. Then we build a new image by cropping or by perspective rectifying the denoised one. From this step, we can expect the document to a real quadrangle. The new document is analyzed and we try to find images, logo or non text element in the documentimage with the aid of an image segmentation. At this stage, we provide deux parts of the document image: the
more » ... text part and the "non text" part of the document-image (images, logos, non ...). The text part of the document-image is enhanced by an original pde's based model that we proposed. The "non text" document is enhanced by classical methods such as retinex processing. Then, we merge both parts of the document image by a poisson image editing. The effectiveness and the robustness of the proposed process are shown on numerical examples in real-world situation (images acquired from cameraphones).
