Note: If the former is used, user will complete parameters through terminal
Run image compression on image with valid extension: {self.validExt}
Algorithms:
pca: Principal Component Analysis
svd: Singular Value Decomposition
Modes:
v: Select a percentage of variance to keep. Only valid if mode=pca.
c: Select a number of components to keep.
q: Select compression level from predefined settings. Only valid if mode=pca.
Compression ranges:
Given mode...
v -> float between 0 and 100
c -> int
q -> Either low, medium, or high quality
Overflow:
1: True, values of pixels on one or more channels may overflow, resulting in cool noise
0: False, prevent cool noise but retain maximum image quality
Optional
Log:
1: True, log data to logs/
0: False do not log data to logs/
Optional
Target:
file name: name with valid extension which will be saved to "output" folder
Optional
Examples:
{self.name} tiger.jpg pca 1 95 1 0 tiger_pca_v_95.tif
