Imageanalysis software

review of relevant image analysis software

These are basic operations which generally don't depend on the content of the image. Simple examples and pointers to Python tools. Use libraries even for simple operations.

common problems and operations

• readers
• RGB values
• geometric clipping
• transparency and backgrounds
• colour scaling and conversions
• file formats (esp. JPEG, TIFF)
• grayscale
• thresholds
• colour2gray or colour2monochrome

preferred formats

We convert into these wherever possible.

• RGB
• PNG
• white background / black

image readers

example code to read images

geometric bitmap operations

Tools (or native Python) to:

• section clipping,

• rotate

• 90/180 rotation (might be required for text)
