Doctor's Handwritten Prescription Recognition using deep learning5 answersDoctor's handwritten prescription recognition using deep learning techniques is an area of active research in computer science. The illegible handwriting of doctors makes it difficult for both the public and pharmacists to understand and process prescriptions accurately. Various approaches, including image processing, machine learning, and deep learning techniques, have been used for handwritten text recognition. Deep learning techniques such as Recurrent Neural Networks (RNNs) and Convolutional Neural Networks (CNNs) have shown promising results in interpreting handwritten texts. One proposed system utilizes optical character recognition (OCR) to transform handwritten or printed prescriptions into electronic counterparts, improving accuracy and reducing misinterpretation. These systems store various features and utilize NLP techniques to enhance recognition accuracy. However, it is important to note that existing models may have limitations in recognizing texts written in languages other than English.
Document forgery detection in handwritten images using deep learning4 answersDocument forgery detection in handwritten images can be achieved using deep learning techniques. Deep learning algorithms, such as convolutional neural networks (CNNs) and generative adversarial networks (GANs), have shown promising results in identifying forged images. CNNs can be trained on datasets of genuine and forged images to learn patterns and features indicative of forgery. GANs, on the other hand, consist of two neural networks that collaborate to generate and classify images, allowing the discriminator network to learn the features of forged images. Additionally, techniques like capsule layers and error level analysis (ELA) can be used to detect forgery in handwritten signatures and identify errors in image compression levels. Hyperspectral imaging, combined with unsupervised feature extraction through a Convolutional Autoencoder (CAE) and Logistic Regression (LR), can also be utilized for document forgery detection. The use of conformable moments (CMs) and deep ensemble neural networks (DENNs) has shown improved performance in detecting forged handwriting in noisy and blurry environments.
How can CNNs be used for handwriting recognition?5 answersConvolutional neural networks (CNNs) are used for handwriting recognition by leveraging their ability to perceive the structure of handwritten digits and automatically extract features. CNNs have achieved breakthrough performance in this field, surpassing traditional systems that rely on handcrafted functions and previous knowledge. Various CNN models with different fully connected layer sizes have been explored to improve recognition accuracy. CNN models have also been trained on datasets such as MNIST and IAM to recognize handwritten digits and words. Additionally, CNN models have been used for Arabic handwriting recognition, achieving promising results on datasets like Hijja and AHCD. Overall, CNNs offer a powerful technique for handwriting recognition due to their ability to perceive structure, extract features, and achieve high accuracy on various datasets.
Can we detect emotion from handwriting using ann?5 answersEmotion detection from handwriting using Artificial Neural Networks (ANN) is a new and active study topic. Handwriting analysis is a multi-level approach that can detect emotions by analyzing the way a person writes. Graphology, the study of identifying human personality through handwriting, can provide rich information about a person's emotional state. Researchers have utilized various machine learning algorithms and approaches to perform computer-aided graphology and understand emotional, mental, and physical states through handwriting. Additionally, a user emotion detection method for a handwriting input electronic device has been proposed, which involves determining a user emotion parameter using an artificial neural network based on handwriting input characteristics. Furthermore, a study has shown that the emotional state of a user can be assessed from digitized handwriting, achieving up to 70% accuracy using a user-dependent classifier. Therefore, it is evident that ANN can be used to detect emotion from handwriting, providing valuable insights into a person's emotional state.
What are the latest advances in deep learning for handwriting?5 answersRecent advances in deep learning for handwriting recognition have focused on the combination of convolutional neural networks (CNNs) and recurrent neural networks (RNNs). These approaches utilize the Connectionist Temporal Classification (CTC) objective function and attention sequence to sequence (Seq2Seq) models. The combination of CNNs and RNNs allows for the recognition of complex objects, such as handwriting, without the need for segmentation. Additionally, the Seq2Seq models are more flexible and suitable for the temporal nature of handwritten text, allowing them to focus on the most relevant features of the input. These advancements have improved the accuracy and efficiency of Arabic word recognition, as well as the detection of forged handwriting in noisy and blurry environments. However, there are still challenges to be addressed in terms of robustness and adaptability in handwritten text recognition.
