摘要： A method and device for removing noise from an image is disclosed. The method includes creating a single dimensional vector for an image through a multi-layer neural network. The method further includes converting the single dimensional vector into a multi-dimensional matrix based on number of layers in the multi-layer neural network. The method includes generating a feature hierarchy based on the multi-dimensional matrix, such that the feature hierarchy comprises a plurality of levels, and each level in the plurality of levels comprises at least one feature associated with the image. The method further includes creating a plurality of segments for the image based on the feature hierarchy, such that each of the plurality of segments includes a set of features associated with the image. The method includes removing each segment comprising noise from the plurality of segments to generate a de-noised image.

摘要： This disclosure relates generally to image processing, and more particularly to method and system for reconstructing an image. In one embodiment, the method includes pre-processing an input image to generate character images corresponding to characters in the input image, determining a local character thickness threshold value for each character image, determining a global character thickness threshold value for the input image based on the local character thickness threshold values for the character images, and reconstructing each character image based on the local character thickness threshold value for each character image and the global character thickness threshold value to generate reconstructed character images. The local character thickness threshold value in a character image may be based on a set of character pixel values in a pre-determined number of segments in the character image. The method further includes re-constructing the input image based on the reconstructed character images.

摘要： A methods and system for creating a presentation is disclosed. The method includes gathering presentation requirements and configuration settings associated with the presentation requirements from a user. The method further includes identifying a plurality of existing slides satisfying the presentation requirements and the configuration settings gathered from the user. Confidence scores are thereafter computed for each of the plurality of existing slides across a plurality of categories. Thereafter, an overall confidence score for each of the plurality of existing slides is determined using: the confidence scores computed for each existing slide across the plurality of categories, weights associated with each of the plurality of categories, and a dynamicity index, when associated with an existing slide. One or more of the plurality of existing slides, for which overall confidence score is below a final associated threshold confidence score, are removed. Thereafter, a list of remaining existing slides is displayed to the user.

摘要： The present subject matter is related in general to the field of image processing, disclosing method and system for evaluating an image quality for Optical Character Recognition (OCR) Image evaluation system receives image comprising optical character data. The image evaluation system determines image parameter value for each of one or more image parameters of the image. The image parameter value for each of the one or more image parameters is determined for plurality of binary image segments identified in the image. The image evaluation system determines suitability value and impact value of the image, based on the image parameter value for each of the image parameters determined for the image. The image evaluation system determines quality score for the image, based on the suitability value and the impact value. The image is transmitted for processing before the OCR, upon determining the quality score to be above overall pre-defined threshold value.
