Abstract

A text correction method and apparatus can take advantage of a greatly reduced number of error-ground truth pairs to train a deep learning model. To generate these error-ground truth pairs, different characters in a ground truth word are replaced with a symbol, not appearing in any ground truth words, to generate error words which are paired with that ground truth word to provide error-ground truth word pairs. This process may be repeated for all ground truth words for which training is to be performed. In embodiments, pairs of characters in a ground truth word may be replaced with a symbol to generate the error words which are paired with that ground truth word to provide error-ground truth word pairs. Again, this process may be repeated for all ground truth words for which training is to be performed.

Abstract

A text correction engine meets different and changing end user requirements, with the ability to change a desired output by providing sufficient amounts of data, and by finetuning the appropriate text correction engine at the point of origin of the data. It is possible to retain confidentiality of data by retraining the base deep learning model at the base deep learning model's point of origin, to improve the base deep learning model's performance, making the base deep learning model more accurate for different contexts. Separate training of an end user model, leaving the base deep learning model intact, streamlines end user model training, and highlights desirable changes in the base deep learning model for further training or retraining.

Abstract

A method is disclosed for eliminating potential video echo effect for a collaboration session that utilizes AR environments. During the collaboration session and in the local AR environment, a contact overlap mask is generated that identifies a content overlap region where the projected remote content superimposes over the physical object placed on the local workspace surface. Based on the contact overlap mask, the local AR environment is temporarily modified throughout a short time period when the projected remote content is prevented from superimposing over the physical object within the content overlap region. A local image is generated based on the temporarily modified local AR environment and sent to the remote workstation for sharing in the collaboration session. By excluding any projected remote content from superimposing over the physical object in the local image, a potential video feedback loop is eliminated so as to eliminate any potential video echo effect.

Abstract

A method and system to generate training data for a deep learning model in memory instead of loading pre-generated data from disk storage. A corpus may be stored as lines of text. The lines of text can be manipulated in the memory of a central processing unit (CPU) of a computing system, using asynchronous multi-processing, in parallel with a training process being conducted on the system's graphics processing unit (GPU). With such an approach, for a given line of text, it is possible to take advantage of different fonts and different types of image augmentation without having to put the images in disk storage for subsequent retrieval. Consequently, the same line of text can be used to generate different training images for use in different epochs, providing more variability in training data (no training sample is trained on more than once). A single training corpus may yield many different training data sets. In one aspect, the model being trained is a deep learning model, which may be one of several different types of neural networks. The training enables the deep learning model to perform OCR on line images.

Abstract

Aspects of the present invention provide a new text location technique, which can be applied to general handwriting detection at a variety of levels, including characters, words, and sentences. The inventive technique is efficient in training deep learning systems to locate text. The technique works for different languages, for text in different orientations, and for overlapping text. In one aspect, the technique's ability to separate overlapping text also makes the technique useful in application to overlapping objects. Embodiments take advantage of a so-called skyline appearance that text tends to have. Recognizing a skyline appearance for text can facilitate the proper identification of bounding boxes for the text. Even in the case of overlapping text, discernment of a skyline appearance for words can help with the proper identification of bounding boxes for each of the overlapping text words/phrases, thereby facilitating the separation of the text for purposes of recognition.

Abstract

A method and system providing an anti-counterfeiting label or mark, using ordinary inkjet printers, take advantage of a phenomenon called a coffee ring pattern, something that inkjet printers. Even the same inkjet printer can output different patterns under different conditions. As a result, the likelihood of reproduction of a particular printer's coffee ring pattern using another printer is so low as to be negligible. It is possible to capture images of the coffee rings using a smartphone camera. The coffee ring approach may be used on any labels or packages on which inkjet printing can be used.

Abstract

Method and apparatus to match bounding boxes around text to align forms. The approach is less computationally intensive, and less prone to error than text recognition. For purposes of achieving alignment, information per se is not as important as information location. Information within the bounding boxes is not as critical as is the location of the area which the bounding boxes occupy. Scanning artifacts, missing characters, or noise generally do not affect bounding boxes themselves so much as they do the contents of the bounding boxes. Thus, for purposes of form alignment, the bounding boxes themselves are sufficient. Using bounding boxes also avoids misalignment issues that can result from stray marks on a page, for example, from holes punched in a sheet, or from handwritten notations.

Abstract

In providing cloud services, key-based security measures specific to a local network are utilized when an internal client terminal logs into the network to access cloud services, and when a remote client terminal connects directly to the cloud services. A cloud service computer references the credential authorization service of the local network, allowing key-based security measures of that network to be applied even when a remote client terminal connects directly to a cloud service computer. By referencing the local credential authorization service, it is possible to provide cloud services to different organizations that administer key-based security measures independently of each other.

In a color to grayscale image conversion particularly method suitable for processing color document images such as forms, the color image is analyzed to determined which of the red, green and blue channels are the most dominant, second most dominant, and least dominant channels, based on the amount of information contained in each channel. Then, coefficients are assigned to the three channels, where the coefficient for the most dominant channel is smaller than the coefficient for the second most dominant color channel, which is in turn smaller than the coefficient for the least dominant color channel. The grayscale pixel value is then calculated using a linear combination of the red, green and blue pixel values weighted by their assigned coefficients. In one example, the ratio of the coefficients for the least dominant, the second most dominant and the most dominant channels is 10:3:1.

Abstract

There is described an image processing apparatus, which makes it possible not only to eliminate the deterioration of the perceptibility, but also to determine the pages being suitable for applying the predetermined image processing. The control section determines specific pages, being suitable for applying a predetermined image processing, based on the attributes detected by the detecting section, so as to apply the predetermined image processing to the specific pages. On the other hand, the control section applies image processing, including a variable power processing, to both the partial image area and the partial character area by employing different magnification factors, so as to generate a size-changed partial image area and a size-changed partial character area, and to arrange both of them into a predetermined imaginary area being smaller than an area of the original image, so as to accommodate them within the predetermined imaginary area.

Abstract

When conveying an envelope, a posture of the envelope is corrected by hitting a closed portion of the envelope, which is opposite side of an opened portion of the envelope, against a nip portion between upper and lower rollers of the pre-registration rollers and the envelope is then conveyed with the envelope being nipped by the upper and lower rollers of the pre-registration rollers. The upper and lower rollers of the pre-registration rollers nip the envelope to remove air from the envelope. When setting an envelope mode to control a conveying speed of the envelope based on a coverage rate of an image to be formed on the envelope, the conveying speed of the envelope is controlled by adjusting a rotation speed of the registration rollers based on the coverage rate of the set envelope mode.
