Brightness adjustment involves scalar multiplication, where each pixel's intensity is modified by a scalar factor. This operation influences contrast and brightness, allowing for fine-tuning of image aesthetics. The study employs numpy library functions to apply scalar multiplication and ensure pixel values remain within the valid intensity range.
Image rotation is achieved through matrix multiplication, where a rotation matrix is applied to each pixel coordinate. This geometric transformation preserves object form while rotating the image by a specified angle. The study utilizes numpy library functions to create the rotation matrix and apply it to the image matrix, enabling flexible rotation according to the desired angle.
The transpose operation manipulates the orientation of pixel values within the image matrix, facilitating tasks such as image flipping and orientation adjustments. By transposing the image matrix, the study demonstrates how pixel arrangements can be altered to achieve different visual effects. Numpy library functions are utilized to perform the transpose operation efficiently.
Image inversion involves changing the intensity of each pixel by subtracting its value from the maximum intensity value. This operation results in an inverted version of the original image, offering unique visual perspectives. The study employs numpy library functions to implement the inversion operation and visualize the inverted image.
