i have to extract the person from the image(mask_crop.png) and overlay it to the other pgm(sample.zip) image. i have already tried thresholding based extraction and intensity based overlay. The results were not that good. Please find the two images attached.

I have the same issue. Here is the sample image, which we want as result:
I have a binary prediction map, which I want to overlay on original image with transparency to see how good the segmentation results are. I have looked into alpha property and also tried imoverlay function. The alpha property method does not work, and imoverlay() overlay maps the binary image as a solid color, thus hiding the original image at pixels positions where the binary map is 1.

Please post your binary image and your original RGB image, preferably as a new question with you as the original poster. The alpha method should work. Not sure what you did but if you post your images, we'll get it working.

Hi I have totally opposite doubt, Actually Im working with this code which overlays the sematic segmented image over the original image. But i want to extract only the sematic image. How can i do so?
C = semanticseg(I,net);
cmap = camvidColorMap;
B = labeloverlay(I,C,'Colormap',cmap,'Transparency',0.4);
figure
imshow(B)
pixelLabelColorbar(cmap, classes);

Save I and C to a .mat file and attach the file here with the paperclip icon.
save('Sanjana.mat', 'I', 'C');
