- Preliminary Information
- Downloading Image
- Differences between the Image (Mac)
and Scion Image (PC)
- ImageJ is not intended to look exactly like NIH Image. Instructions
specific to ImageJ are in green.
- Introduction to Image . On
line introduction to IMAGEJ
- Noise removal
- Shot noise - add and remove with median
- Visual Comparison of mean and median
- Histograms, .
- Basic Histogram, cutting and pasting
images, pixel and LUT inversion, contrast enhancement.
- Histograms after Filtering (with comments on Signal-to-Noise)
- Image Size (Scale & Rotate)
- Image Aspect Ratio
- Flatten Illumination (background subtraction)
- Inversion (black and white vs. up
- Mach Bands
- Background level
- Arc Radius (illustrates drawing with
- Sharpen (Laplacian or Unsharp Masking)
- RGB Color
- RGB Tiff Example (tree). Loading a 24 bit
color image into a stack.
- Koala Example. Making an 8 bit color image
from three gray level images.
- Xray Maps Example. Loading and tiling
seven small gray level images. Making an 8 bit color image from three
- Boron Stack (including Stereo Analyglyph)
- Percent Area & Particle sizing.
