TIMESTAMPS
Real-Time Image Acquisition and Processing for Amber Infrared Cameras.
ImageDesk is an image acquisition and processing system designed for
Amber's broad range of high-performance infrared cameras. The system
includes a high-speed digital acquisition board and a Pentiumâ„¢-based
software package. ImageDesk is a powerful tool for scientific, R&D,
and industrial applications that require high bandwidth performance and
flexibility.
Hardware Features:
- Frame grabbing at up to 48 Mbytes/second
- 50 MHz TI TMS320C40 DSP
- Up to 256 Mbytes Acquisition Memory ( 16 Mb standard)
- 90 MHz Pentium-based host computer system.
Software Features:
- Live Acquire mode supports acquisition and display at rates up to 15 frames/second.
- Live Acquire processing tools include line plots, pseudo color, intensity calibrations, and histograms.
- VCR-like controls for Play, FF, REW
- Image Sequence mode allows real-time acquisition of contiguous data.
- Math functions over sequence by an array or constant.
- Control frame subtraction.
- Time profile of a region of interest for a sequence.
- Gallery function provides visual image data base management.
- Full support of geometric measurement, blob counting, sizing, and classification.
- Complete image analysis and enhancement tool libraries.
- Image enhancement.
- .FTS (FLEXIBLE Transport System) file format support for multi-frame I/O.
- Sequence merging and ROI cut.
- Macro language allows recording of sessions and playback in 100% Visual Basic syntax.
- Assign macros to function keys and control icons.
Analysis:
- Calculate line or area histograms, and line or thick profiles.
- Percent area of multiple threshold levels.
- Display data or histograms.
- Define and manage multiple areas of interest in a single image.
- Calculate statistics.
- Analyze RGB or HSI content of color images.
- Combine image with background protection for precise intensity or optical density measurements.
- Background corrected line profiles.
- Output intensity map in ASCII format
Enhancement:
- Enhance color and contrast using equalization, gamma correction, contouring, and thresholding.
- Background subtract.
- Use Top-Hat, Well, hi-pass, low-pass, Sobel, edge detection,
Laplace, Roberts, erosion, dilation, opening, closing, thinning,
watershed, and user defined filters.
- User-selectable kernel shapes and sizes for morphological filters.
- User-selectable scale and boost.
- Set number of filter passes and filter strength. Calibration.
- Calibration.
- Work with intensity or optical density (OD) measurements.
- Use up to 20 reference points to correct for non-linear intensity or OD.
- Calibrate special units based on reference length in image.
- Save and recall all calibrations.
- Capability for thermography transform to be applied to images.
Given user entry of emissivity, and user calibration of the camera,
on-screen data may be transformed to temperature.
Color Channel Processing:
- Extra red, green, and blue, or hue saturation and intensity channels for processing.
- Merge channels for processing.
- Switch or copy channels within an image.
- Use color information to separate objects from background.
- Isolate a group of colors for processing and analysis.
Annotator:
- Add text, simple graphics, and arrows.
- Modify palette or colors.
Operations:
- Perform special (bi-linear scale, decimation, rotate, warp,
transpose, reflect) logical arithmetic, image alignment, and background
correction operations.
- Image registration.
Fast Fourier Transform (FFT):
- Create direct and inverse transforms.
- Edit spectrum including low-pass, high-pass, unsharpen, spike cut, spike boost.
- Save and reload data.
