I would like to remove the black area(background) of these images so that I can segment only the targetted region, which is the circle. Please help, thank you in advance.

You can direct thresold the largest black area. Here the shown code is quite lengthy, but it is easier to understand.
bwImage=imbinarize(rgb2gray(rgbImage));
mask=bwareafilt(~bwImage,1);
R_data=rgbImage(:,:,1);
G_data=rgbImage(:,:,2);
B_data=rgbImage(:,:,3);
R_data(mask)=255;
G_data(mask)=255;
B_data(mask)=255;
result=cat(3,R_data,G_data,B_data);
figure,imshow(result);

rgbImage=imread('Imagefilename.jpg');

%After this paste previous code
