[Retracted] Enhanced Watershed Segmentation Algorithm-Based Modified ResNet50 Model for Brain Tumor Detection
Table 1
Parameter used in augmentation step.
S. no.
Parameter
Value taken
Remark
1.
Rotation_range
15
By specifying the rotation_range, image is randomly rotated.
2.
Width_shift_range
0.05
The width_shift_range is a floating point number; the image randomly shifts, either towards the left or the right by a given value.
3.
Rescale
1/255
Scales the image as per the given value
4.
Shear_range
0.05
Shear transformation slants the shape of the image. This is different from rotation in the sense that in shear transformation, we fix one axis and stretch the image at a certain angle known as the shear angle.
5.
Height_shift_range
0.05
The image is shifted vertically instead of horizontally.
6.
Brightness_range
[0.1, 1.5]
The brightness_range specifies the range for randomly picking a brightness shift value from.
7.
Horizontal_flip
True
On a random basis, the image is horizontally flipped.
8.
Vertical_flip
True
On a random basis, the image is vertically flipped.
