To optimize contrast enhancement digitally, it is imperative that the microscope optics and the camera are adjusted so that the full dynamic range of the system is utilized.
To optimize contrast, a black background was used for white mice, and a white background was used for agouti and black mice.
At the forefront of this field are efforts to optimize contrast at low electron dose, in order to locate and characterize macromolecular complexes within tomograms of cells and tissues.
To optimize contrast, acquisition time, and resolution, the scanning sequence was set to a voltage of 50 kV, a current of 300 µA, and an exposure time of 500 ms. A rotation of 210° in 180 rotation steps led to a resolution with an effective pixel size of 53 µm.
To illustrate the impact of optimal contrast pulses, a RF pulse is computed to optimize the contrast between the rat brain (minimize) and surrounding muscles (maximize).
The cost function ((mathcal {C})) that optimizes the contrast must maximize the difference between the transverse magnetization norms of 2 samples a and b, at the end of the control time (t=t f ).
Thus the method optimized the contrast resolution by adaptively selecting the samples of the excitation.
In the current literature, the majority of IVA algorithms are based on optimizing certain contrast functions, cf. [5, 7 9].
An important issue is the use of this method in clinics to optimize the contrast of human body imaging.
The new TVs have an "Intelligent Sensor" that claims to automatically calibrate and optimize brightness, contrast, white balance, and color based on the ambient light in a room.
