LEAD Technologies Advances Document, OCR and Medical SDK Technology for Windows and Linux

LEAD Technologies Releases Substantial LEADTOOLS Update for Linux, Document, OCR and Medical SDK Technology

LEAD Technologies has released a significant upgrade to its LEADTOOLS version 19 product line that touches a wide range of technologies including OCR, document imaging, medical imaging and PACS.  “This release encapsulates LEAD’s commitment to its broad customer base and demonstrates the skill and diversity of our programmers and imaging experts, all of which continue to ensure LEADTOOLS’ position as the world-leading imaging SDK,” stated Jordan Shields, Vice President, LEAD Technologies.  These updates are freely available to all registered LEADTOOLS Version 19 and annual maintenance customers.

New Java Libraries for Windows and Linux – Multiple coding teams at LEAD Technologies combined their efforts with a single purpose to resolve numerous customer requests for Java libraries for LEADTOOLS.  These Java libraries expand LEADTOOLS functionality for Linux with support for OCR, Documents library services, Document Writers, Document Converter, vector and document formats such as PDF and DOCX, and SANE scanning.  Additionally, the libraries provide a common programming interface to develop applications for Windows and Linux.  

Document Viewer on Linux – The LEADTOOLS Document Viewer includes rich document viewing features such as text search, annotation, memory-efficient paging, inertial scrolling and vector display.  LEADTOOLS' Document Viewer supports viewing PDF, MS-Office, AutoCAD DWG/DXF and many vector/raster formats.  Developers and administrators can host all of the services required by the LEADTOOLS Document Viewer using Java services on Linux servers.  

This release encapsulates LEAD's commitment to its broad customer base and demonstrates the skill and diversity of our programmers and imaging experts, all of which continue to ensure LEADTOOLS' position as the world-leading imaging SDK,

Vice President

Document Writers Available for Linux – LEADTOOLS Document Writers are now available for Linux.  LEADTOOLS’ Document Writers create PDF, PDF/A, DOCX, RTF, TEXT and ALTOXML from SVG input.  Other technologies within LEADTOOLS that create SVG, such as OCR, can leverage the Document Writers to save these document formats.  

Document Converter Available for Linux – With LEADTOOLS Document Converter technology, developers can create powerful, automated document conversion, archival and delivery systems.  Under the hood, LEADTOOLS’ Document Converter technology uses a combination of raster, OCR and Document Writers technologies to convert images and documents to PDF, PDF/A, DOCX, RTF, TEXT and SVG.  

Innovations Applied to the Advantage OCR Engine – The OCR specialists at LEAD Technologies continue to enhance the top-notch performance of the LEADTOOLS Advantage OCR engine in both accuracy and speed.  Sweeping improvements have been made for several core features including Latin and Korean language recognition, auto-zone for images with noise and graphics, and preprocessing of noisy images.  Generated documents more closely resemble the original images through enhancements to foreground and background color detection, font type recognition, and a brand-new serif and sans-serif font typeface detection.  LEAD Technologies continues to dedicate and add significant resources to meet the ever-growing demands of the market.  

HTML5 Medical Viewer is Better than Ever – Numerous customer requests have been included in this release such as adding structured display and templates (custom and built-in) technology to the HTML5 Medical Viewer.  With these features, the end-user can design custom display templates choosing from three ways to arrange series images: sequentially, DICOM instance number or custom JavaScript function.  Users can save the templates to a LEADTOOLS storage server as a DICOM structured display dataset; the LEADTOOLS Medical Viewer will use them to render series. 

Additional features added to the HTML5 Medical Web Viewer include rendering encapsulated PDF documents in a viewer frame, and users can now upload DICOM to the server directly from the viewer.

Besides adding new features, LEAD Technologies continues to refine the HTML5 Medical Viewer and related services.  This latest update provides many speed upgrades, including load, window-level, image processing, and cine.  These optimizations open the door to higher quality MPR output and real-time window-level of large projection radiographs such as mammography and x-ray images. Other enhancements include better spyglass functionality and support to load all types of images such as CT, MR, and MG. Stack functionality has been enhanced to handle large volume stacks such as CT and MRI, and perform synchronization on two large stacks of the same anatomy.  The viewer can now generate high quality orthogonal slices and use a 3D cursor for smooth MPR navigation. Additionally, the probe tools have been strengthened by adding Hounsfield (HU) scale support.  

Multi-Resolution and Tiled Image Technology Added to HTML5 Medical Viewer – At the core of several of the HTML5 Medical Web Viewer enhancements is the new multi-resolution and tiled image (MRTI) technology, which optimizes the delivery of large, extremely high-resolution (up to 1TB) images, including microscopy and pathology images. MRTI intelligently serves a portion and resolution of the image based on the specific client request.  This saves bandwidth, reduces memory requirements, and increases the overall efficiency of the entire system.  

WADO and DICOMweb Interface – LEADTOOLS now provides extensive support for DICOM WADO, including WADO-URI, WADO-WS and DICOMweb (RESTful DICOM Services). Developers can use the API to directly access patient/study related data stored in third-party PACS or expose PACS data to direct third-party access using the DICOM defined HTTP protocol standard, including DICOM data storage (STOW-RS) over the web.

In addition, LEADTOOLS includes DICOMweb support for the LEADTOOLS high-level PACS Framework. This enables third-party systems to directly query (QIDO-RS), retrieve (WADO-RS), and store (STOW-RS) DICOM object over the web to its DICOM storage system using DICOM WADO protocol from anywhere, thereby removing the domain boundary limitation. 

Advanced J2K Technology – The compression experts at LEAD Technologies have optimized the loading of heavily tiled J2K and TIFF J2K files.  Additionally, they have expanded TIFF J2K technology in LEADTOOLS by adding functions to enumerate and load sub-resolutions of J2K data encapsulated in TIFF.  

New Features Added to Annotation Technology – Snap-to-grid and alignment UI features have been added with this release.  These features provide image markup formatting features usually only found in word processing and presentation applications.  

New Image Processing Functions – Salt & Pepper Noise Removal and UnWarp image processing functions are now available in LEADTOOLS. The UnWarp function removes the distortion in an image of a cylindrical object, as if removing a label from off of the cylinder and flattening it out.
