To visualize the two images together, we do the following: 1. An matplotlib.image.FigureImage instance is returned. Use the influence map pixels to control the transparency of each pixel in the green image (Figure 6). and a simple luminanace image just has one value (and is thus only a 2-d array, not a 3-d array) for RGB and RGBA images matplotlib supports float32 and uint8 data type. The figure patch will also be transparent unless face color and/or edgecolor are specified via kwargs. Since it's a black and white image, R, G, and B are all similar. img = im.convert("RGBA") Notice that the background of the plot itself is transparent now. The image in Word is identical as in pdf. We can also save plots in other formats like png, jpg, svg, pdf and many more. Matplotlib allows you to regulate the transparency of a graph plot using the alpha attribute. black and white.
