Talking about the compression perception (V): Single pixel Camera

Some theoretical knowledge of compression perception is described earlier, and here is the simplest and first application of compression sensing, single Pixel camera.

1, single-pixel camera model and structure:

As shown in the following:

PD is a light sensing device (i.e. single pixel), corresponding to Yi in the formula;

The scene image corresponds to the f in the formula;

DMD is a digital micro-mirror array, which is used to generate a measurement matrix, each of which corresponds to a single line of φ in the formula.

The actual experimental scenario:
