The research is geared to enable a precise and accurate automatic assessment of microscope focus quality. The paper Assessing Microscope Image Focus Quality With Deep Learning introduces a deep neural network model that could identify on a small 84 × 84 image patch (about several times the area of atypical cell), the extent of the image blur and whether the image blur is even well-defined, which implies if the image patch is a background. ![]() Google’s deep learning researchers have automated a technique to rate focus quality which can enable the detection, troubleshooting and removal of such images. According to a post by Google, despite having autofocus systems on state-of-the-art microscopes, poor configuration or hardware incompatibility can produce substandard images, which results in quality issues. The research deals with an important challenge of dealing with out-of-focus images. Now, Google’s current research has found a way for scientists eager to use cutting-edge DL techniques for advanced image analysis work. Handling out-of-focus images with the help of a pre-trained TensorFlow model with plug-ins from the Google Accelerated Science teamĭeep neural networks have already played an important role in a host of tasks such as detection, segmentation, and classification in microscopic image analysis.Basics of machine learning for analysing microscope images. ![]() Google’s latest research covers two important aspects: ![]() There is a renewed interest in medical image computing, and here, deep learning has proved to be effective in its ability to handle complex microscopic images. Deep learning has emerged as a leading machine learning tool in computer vision and has attracted considerable attention in biomedical image analysis. ![]()
