Decoding
Decoding
The process of converting a coded message back to its original form.
Stable Signal Processing Characteristic
Stable Signal Processing Characteristic
Characteristics of signal processing methods that ensure consistent results, minimizing noise and errors in the analysis. This includes accurate segmentation avoiding image artifacts.
Image Registration Transformation
Image Registration Transformation
Transforms multiple images into a common coordinate system to align them. It does not adjust pixel intensities or perform frequency domain transformations.

Study Notes
Encryption and Decoding
- Encryption uses rules to protect messages, only sender and receiver can understand.
- Decoding reverses the encryption process, revealing the original content.
Signal Processing
- Stable signal processing is characterized by consistency, noise reduction, and accurate segmentation. It avoids image artifacts.
Image Transformations
- Geometric transformations alter the spatial layout of an image.
- Image registration aligns multiple images to a common coordinate system.
Medical Image Processing
- Pre-medical image processing focuses on improving medical data quality for visualization and analysis.
- MIQA (Medical Image Quality Assessment) is used to evaluate medical images.
Image Evaluation
- Subjective evaluation involves human experts rating image quality, a time-consuming method.
- MIQA uses human evaluators to provide a "gold standard" for quality assessment.
Image Quality Assessment Metrics
- Entropy is a measure of randomness or disorder.
- Objective metrics for image quality, often numerical measurements.
Image Compression
- Image compression reduces file size by removing unnecessary information but sometimes loses data.
- Lossy compression removes data permanently and lossless compression preserves every bit of data.
- Noise removal methods such as median filters are used to improve image quality. Compression techniques reduce bandwidth required for image transmission.
Noise Removal
- Noise in images can be reduced by filtering methods, such as median filter.
- Noise reduction improves diagnostic clarity.
