What are brightness and contrast in image processing?
Brightness and contrast represent a way to adjust an image. They come from the display technology, being common controls in all monitors. The color brightness/contrast are similar to the grayscale counterparts, in most cases being applied to all channels (even if from the physical point of view this is wrong - a transformation into HSI with adjustment of the I component would be correct -. For a grayscale image, brightness represents an image adjustment where a constant value is added to all pixel values. The contrast adjustament is a multiplication of the pixel values with a constant. Most of the image processing programs use a different scale, for example from 0 to 10. If you wish to experiment with it, you can do it photoshop, gimp. To apply a brightness/contrast correction to a bunch of images is easier with an image converter like AZImage - see related link.
Why input is voltage and output is current in fet?
The input is a Gate that is essentially infinite impedance, so no current. The output is essentially the resistance between Source and Drain, which controls the current flowing through it.
If resistance is constant and voltage increases what happens to current?
You have it backwards, the resistance controls the current not the current controls the resistance. I = E/R . Your question should read, "If the voltage is constant and the resistance in the circuit is increased what happens to the current?" Say the voltage is 120 volts and the resistance is 30 ohms, I = 120/30 = 4 amps. Now we double the resistance to 60 ohms, then I = 120/60 = 2 amps. So now you can see if you increase the resistance the current drops.
What are the VBA Controls?
You can configure your own controls. Just go to Options->Joypad->Configure->1... and you can set all the controls there.
When engineering controls are not adequate what forms of controls can be implemented?
physical and administrative
How does a slide dimmer control the brightness of a light fixture?
A slide dimmer controls the brightness of a light fixture by adjusting the amount of electrical current flowing to the light. Sliding the dimmer switch changes the resistance in the circuit, which in turn regulates the amount of power reaching the light bulb, resulting in varying levels of brightness.
What controls current?
The load resistance in the circuit controls the current flow.
Where can you find an electrical schematic for the air condintioning pump and controls on a 1998 Ford Escort ZX2?
In a motor manual.
Which parts of the microscope controls the brightness?
The brightness on a microscope is controlled by the light source, usually a light bulb or LED located beneath the stage or within the body of the microscope. The intensity of the light can be adjusted using a control knob or dial typically located on the base or body of the microscope.
What controls the brightness of the digital dash on a 1986 corvette Everything works except the brightness?
The dimmer switch near/on the headlight switch is a potentiometer and it controls the dash light intensity, as well as manually turns on the interior lights at the high(bright) end.
Where does the dimmer wire go on a after market radio?
It would go to the dimmer that controls the brightness of the dash lights.
What is stepped resistor?
The resistance that controls a heater motor in the electric system .
How do you reset heads-up display on 2003 Corvette?
On the upper left side of your dash there are controls for the elevation and brightness.
What is a iris diagram for a microscope?
An iris diagram for a microscope is a schematic representation of the iris diaphragm, a component that controls the amount of light entering the microscope. The diagram typically shows how the iris diaphragm can be adjusted to regulate the diameter of the light beam, thereby controlling the brightness and contrast of the specimen being viewed. This feature is crucial for achieving optimal image quality and detail in microscopy.
Why won't the dashboard instrument and center console lights turn on in a 1996 Chevy Cavalier?
You have a blown instrument lights fuse or it is just turned off. There is a rheostat that controls the brightness of the lights. Find it and adjust the brightness.
How can I adjust the brightness of a lamp using a dimmer?
You can adjust the brightness of a lamp using a dimmer by turning the dimmer switch up or down to increase or decrease the flow of electricity to the lamp, which controls the amount of light it emits.
What do you call a substance that offers resistance?
A substance that offers resistance is called a resistor. It is a component in electronic circuits that limits or controls the flow of electric current.
