The edge detection block
The "Edge Detection" block from the "Analysis&Enhancement" group of the Video and Image Processing Blockset (Please refer to Figure 1).
The Edge Detection Block
This block will enable you to simulate the edge detection procedure in the input image using the Sobel, Prewitt, Roberts, or Canny methods.
If the selected method is Sobel, Prewitt, or Roberts, the Edge Detection block finds the edges in an input image by approximating the gradient magnitude of the image. The block convolves the input matrix with the Sobel, Prewitt, or Roberts kernel. The block output can be either the result of this convolution operation (two gradient components of the image) or a binary image, obtained by comparing the convolution result against a threshold. If a pixel value is ‘1’, in this binary image it is an edge. Please refer to Figure 2
The Edge Detection Block Configuration Window for Sobel, Prewitt and Roberts Methods
If the selected method is Canny, the Edge Detection block finds edges by looking for the local maxima of the gradient of the input image. It calculates the gradient using the derivative of the Gaussian filter. The Canny method uses two thresholds to detect strong and weak edges. Please refer to Figure 3.

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

Where is quantity of cut flower produced, I is labour input and K is fixed capital input (K-5). Determine the average product of labour (APL) and marginal product of labour (MPL)
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

What do you think is more important to focus on when considering inequality ?
sir...I just want to ask one question... Define the term contract curve? if you are free please help me to find this answer 🙏
Asui
it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

thank you so much 👍 sir

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
