## Abstract A novel, inexpensive technique for the detection of concealed metal objects is presented and discussed. It is shown that an indirect holographic method, usually employed at optical frequencies, can be adapted to image objects at microwave frequencies. The practical results successfully
## Abstract Lossy transform compression of images is successful and widespread. The JPEG standard uses the discrete cosine transform on blocks of the image and a bit allocation process that takes advantage of the uneven energy distribution in the transform domain. For most images, 10:1 compression
