This simple step by step guide shows you how you can seamlessly blend two images together using Photoshop. STEP 1: Open the two images as separate documents in Photoshop.   STEP 2: Now we will have to combine the two images into one document. This can be done by using the move tool "V" and dragging one image into the other document, the dragged image will make a new layer in the first one. STEP 3: To Add a mask Click on the add mask button as shown in the Read More

There are several different types of traffic cameras. Some types of traffic cameras are only focused on traffic patterns and traffic density. Other types of traffic cameras are placed in locations where traffic infractions commonly occur to capture traffic incidents and record the details for punitive purposes. Cameras for Traffic Monitoring Cameras for traffic monitoring are placed in locations where there are complex intersections, traffic congestion, or locations with weather hazards. The cameras used for such purposes are digital and transmit low resolution pictures from a pole usually about 30 Read More

An algorithm which is used to create a minimum spanning tree is attributed to Kruskal’s algorithm. The nodes of the graph are initially considered as n distinct partial trees with one node each. At each step of the algorithm, two distinct partial trees are connected into a single partial tree by an edge of the graph. When only one partial tree exists (after n-1 such steps), it is a minimum spanning tree. The concern is what connecting arc to use at each step. The answer is to use the arc Read More

Step 1: Open any Image in photoshop and prepare it with the resolution and dimension you want in your final image. Step 2: First create a copy of your image by selecting the Layer via Copy option in the Layer Menu. Now we have 2 Layers first is Background while the second is Layer 1. Step 3: Select the Desaturate option from the Image Menu as shown below. This will make the photograph black and white. Step 4: Now we again make a duplicate copy of Layer 1 by again Read More

In order for clients to establish Terminal Services sessions on a server, listener connections have to be configured on the particular server. A listener connection can be configured for only RDP (Remote Data Protocol) over TCP/IP. One listener connection can be configured for a network interface card (NIC) in the Terminal Services computer. The Terminal Services Configuration tool creates new listener connections to change configuration settings on existing listener connections and to configure server policy settings. While it is recommended to configure Terminal Services connections through Group Policy, the Terminal Read More

Computers usually display the “No Audio Device Error” message when it does not detect any properly working audio device attached to it. Users will not hear any sound from their computer when this message appears. Only the computer’s internal speaker makes bleeping sounds. When this message appears on the screen, check the computer’s BIOS and ensure that the audio is set to “auto” mode. Also, check if the correct drivers that the audio device attached to the computer needs in order work properly are installed. Audio Device Drivers The most Read More

What is CDP? CDP is the Cisco Discovery Protocol. It is a Cisco Proprietary Protocol that discovers and shows information about directly connected Cisco devices. CDP works on layer two (Data Link layer) of the OSI Reference Model. Cisco Discovery Protocol (CDP) works only with the Cisco manageable devices such as Cisco Catalyst Switches and Cisco Routers and Access Server. It is a useful utility of Cisco IOS that runs on the routers with the Cisco IOS version 10.3 or later and Cisco switches and hubs. CDP is basically network Read More

Reed-Solomon is an algorithm for Forward Error Correction (FEC). Reed-Solomon was introduced by Irving S. Reed and Gustave Solomon of MIT Labs in Polynomial Codes Over Certain Finite Fields, which was published in the Journal of the Society for Industrial and Applied Mathematics in 1960. Reed-Solomon does not specify a block size or a specific number of check symbols. These variables can be set to the best variables for each transmission medium. DVB uses Reed Solomon coding configured to use blocks of 188 information symbols and 16 check symbols, which Read More

An ISO file is a type of archive file that allows users to copy the contents of an entire drive or disk. ISO files are uncompressed and contain many other files that have all been collected together for fast and easy transfers. ISO files are often used to store files from a CD or DVD so that they can be easily transferred across the Internet and then burned to a new disk when the user extracts the files. ISO software allows users to create ISO files, burn them to disks, as Read More

A fiber optic connector (optical fiber connector) is a small glass or plastic device that is placed at the end of a fiber optic cable in order to allow light from the cable to enter another device. Fiber optic connectors are often spring-loaded and align the core of each fiber so that they are all directly touching the receiver. This allows light to be contained within the fiber optic cable rather than being let out into the air, in which case data would be lost. While fiber optic connectors are Read More
