Image Processing with ImageJ

Abstract: Discover the incredible possibilities of ImageJ, from basic image processing to macro and plugin development Overview Learn how to process digital images using ImageJ and deal with a variety of formats and dimensions, including 4D images Understand what histograms, region of interest, or filtering means and how to analyze images easily with these tools Packed with practical examples and real images, with step-by-step instructions and sample code In Detail Digital image processing is an increasingly important field across a vast array of scientific disciplines. ImageJs long history and ever-growing user base makes it a perfect candidate for solving daily tasks involving all kinds of image analysis processes. Image Processing with ImageJ is a practical book that will guide you from the most basic analysis techniques to the fine details of implementing new functionalities through the ImageJ plugin system, all of it through the use of examples and practical cases. ImageJ is an excellent public domain imaging analysis platform that can be very easily used for almost all your image processing needs. Image Processing with ImageJ will start by showing you how to open a number of different images, become familiar with the different options, and perform simple analysis operations using the provided image samples. You will also learn how to make modifications through ImageJ filters and how to make local measurements using the selections system. You will also find the instructions necessary to record all the steps you perform so they can be saved and re-run on the same image to ensure analysis reproducibility. Finally, you will get to know some different ImageJ plugins and will learn how to implement your own. What you will learn from this book Install and configure ImageJ and its plugins Open different image formats Move around the image, zoom in and out, and obtain pixel values Master the different selection tools Plot the image profile and understand the histograms Handle 3D and 4D images Use the macro recording system Create your own macros beyond the recorder Build your own plugins using the ImageJ editor Integrate ImageJ with the Eclipse IDE to improve the plugin development process Approach The book will help readers discover the various facilities of ImageJ through a tutorial-based approach. Who this book is written for This book is targeted at scientists, engineers, technicians, and managers, and anyone who wishes to master ImageJ for image viewing, processing, and analysis. If you are a developer, you will be able to code your own routines after you have finished reading this book. No prior knowledge of ImageJ is expected.

Multiresolution digital imagery photofinishing system

Abstract: A photoprocessing, photofinishing apparatus enables an unskilled consumer to personally customize and obtain high quality prints of photographic images without the intervention of a skilled technician. It also provides for the storage and retrieval of high resolution digitized color still images for playback to a variety of reproduction devices. The apparatus comprises a high resolution film scanner (12) which scans 35 mm film and outputs high resolution image signals. These signals are digitized and coupled to a host image data processing unit (14), which stores each image file in a multiresolution, hierarchical format that facilitates retrieval of images for reproduction by a variety of devices the resolution of which may vary from device to device, such as a low/moderate NTSC television monitor (16) or a very high resolution color thermal printer (24). The host processor is coupled to an interactive display terminal, through which the customer may manipulate a low resolution version of a selected image file. The apparatus may also be used by a skilled photofinishing minilab operator to produce a permanent record of images that have been digitized from one or more photographic image sources. In this application, the host computer may be coupled to drive an optical compact disc recorder (18) which writes each hierarchical image file and an appended header file to an optical compact disc (20). The customer may then play back the disc on a CD player modified for display on a home television monitor.

Multi-format television reciever

Abstract: A television system 106 and display method for receiving and displaying television broadcasts having various formats. The television system resizes (106) the various received image formats for display on a common display device. Images are resized horizontally by altering the rate at which data is sampled by the television (106). Images are resized vertically by using vertical scaling algorithms which alter the number of lines in an image. Format detection may be done automatically by decoding information contained in the vertical interval of the television broadcast signal, or by counting the number of lines in each frame. The input format may be indicated by a viewer.

Computer system with enhanced user interface for images

Abstract: A computer system and method are presented that enhance a user experience when viewing images displayed on the computer. The system includes a user interface for the computer that displays a number of thumbnail images that are small representations of image files existing on the computer. The thumbnail images are arranged in alignment with one another, such as at the bottom of a viewing window. An enlarged preview image is positioned adjacent the thumbnail images. The enlarged preview image corresponds to a selected thumbnail image and is a larger representation of an image file corresponding with the selected thumbnail image. A control is displayed in the window that enables the user to iterate through the thumbnail images in at least one direction. As the user iterates through the thumbnail images, the enlarged preview image changes correspondingly.

Method and system for storing calibration data within image files

Abstract: A system and method for storing, within an image transfer medium, an image and image-specific data associated with the image includes obtaining the image-specific data from a probe such as a borescope or endoscope, obtaining the corresponding image, choosing a specific image transfer medium, writing the image to the medium, and writing the image-specific data to a marker in the medium. In this manner, storing a combination of image data and one or more of system calibration data, overlay replacement data, and audio comment data in a single file of either a non-standard file format or a standard file format that does not explicitly support the inclusion of these data types is possible.
