Transcript: The GAME!!! EL JUEGO!!! In this game we will be matching Spanish words and English words together. The rules to this game are very simple. First you lay out all of the cards face down. Once you have layed out all of the cards you have to take turns flipping over the cards until you get a match. Then on the bottom of the card their is the Spanish word for an animal and the picture of the word. On a different card is the english word and picture for the spanish word.
Transcript: DESIGN GOAL OBJECTIVE PRINCESS MEMORY GAME INTRODUCTION INTRODUCTION Games that require players to match similar elements. As the name implies, participants need to find a match for a word, picture, or card. For example, students place 30 word cards; composed of 15 pairs, face down in random order. Each person turns over two cards at a time, with the goal of turning over a matching pair, by using their memory. This is also known as the Pelmanism principle, after Christopher Louis Pelman, a British psychologist of the first half of the 20th century. OBJECTIVE OBJ1 OBJECTIVE 1 • To train visual memory OBJECTIVE 2 • Show the users how good their visual memories are and suggest strategies for improving their memory skills. OBJ2 OBJECTIVE 3 • To Improve concentration OBJ3 OBJECTIVE 4 • To increase short term memory OBJ4 OBJ5 OBJECTIVE 5 • To increase attention to detail • To improve the ability to find similarities and differences in objects OBJECTIVE 6 OBJ6 • To help to classify objects that are grouped by similar traits OBJECTIVE 7 OBJ7 TARGET USER The main target is for children from the age of 4 to 7 years old. However, for any age you can play this game. TARGET USER/PLAYER DESIGN GOAL The design goal of this game is to develop a game that can train users memory hence to boost their visual memory storage capacity in a playful way. When using this game , the users memory can memorize the location of different cards. Interface Memory Game Sketch the story board Interface 1 Interface 2 QUESTIONNAIRE Result of interview or questionnaire Respondent 1 Respondent 2 Respondent 3 Respondent 4 Respondent 5 CONCLUSION CONCLUSION In conclusion, this game is quite entertaining to fill in the free time. With a simple way to play and attractive appearance, this game can be played by all ages. The only disturbance is the presence of advertisements in the form of videos that cannot be skipped, so players must see the ad videos with an average duration of 15 or 30 seconds. In addition, matching Images are available for the Android and iOS operating systems.
Transcript: Matching Domino Game The children around 6-8 years interested in fun and challenge games. They can learn and develop their skill by themselves to improve both their brain and body. When they play game. Most children play with their friend.Therefore, they will get new relationship. So we make a game, that suitable for children of this age. Our game is similar to Domino, but little differently, we change from colored dots to glossaries and images

Image pyramid Multi-angle matching Advanced method grayscale-based matching Grayscale-based matching Edge-based matching Edge-based matching Methodology Measures of matching Template matching measures Measure of match between two images is considered to be a metric that indicate the degree of similarity or dissimilarity between them. Measures of match Measures of match: 1.Based on optimal path searching: Representation: Representing template by a sequence of measurement vectors: Measures of match: A grid with I points (template) in horizontal and J points (test) in vertical. Each point (i,j) of the grid measures the distance between r(i) and t(j). Each path is associated with a cost: K : number of nodes across the path Measures of match: The optimal path is constructed by searching among all allowable paths. The optimal node correspondence, between the test and reference patterns, is unraveled by backtracking the optimal path. Measures of match: 2. Euclidean Distance: I : gray level image g : gray-value template of size n * m (r,c) : top left corner of template g Measures of match: 3. Edit Distance: Dealing with patterns that consist of sets of ordered symbols. Wrongly identified symbol ("befuty" instead of "beauty") Insertion error ( "bearuty") Deletion error ("beuty") Measures of match: 3. Edit Distance: The similarity between two patterns is based on the cost of converting one to another. if having the same length = number of different symbols D(A,B) = minimum total number of changes C, insertions I ,and deletions R required to change pattern A into pattern B. Measures of match: 3. Edit Distance: equality deletion change insertion Measures of match: 4. Measures based on correlation: to find whether a specific known reference pattern resides within a given block of data. target detection, robot vision, video coding. Steps: 1. Move the reference pattern to all possible positions and compute the similarity . 2. Computing the best matching value : Measures of mismatch: based on the pixel-by-pixel intensity differences between the two images f and g. Measures of mismatch Measures of mismatch Measures of mismatch: 1. Root mean square distance(RMS): 2. Sum of absolute differences (SAD): Diff(xs,ys,xt,yt) = |Is(xs,ys)-It(xt,yt)| Problems with template matching: problems with template matching problems Problems with template matching: 1. The template represents the object as we expect to find it in the image 2. The object can indeed be scaled or rotated 3. requires a separate template for each scale and orientation 4. too expensive, especially for large templates 5. Sensitive to: -noise -occlusions Template matching applications: Template matching applications 1. Template matching with various average face pyramid levels 2. 3D reconstruction 3. Motion detection 4. Object recognition 5. Panorama reconstruction
Transcript: object location detection in the images . robot path registration.  To distinguish the matching territory, we need to look at the template image against the source image by sliding it. By sliding means, by moving the patch's one pixel at once left to right and top to bottom. Matching result cross correlation Load the template image and source image. Matching result Detected point This technique matches a template respect to its mean against the image with respect to its mean. so a flawless match will be 1 and an immaculate mismatch will be –1. a value of 0 just implies that there is no connection or irregular arrangements.

Figure 1.7 Figure 2.2(b) RESULTS For every pixel position in the overlay, the template pixel value will be multiplied by the source image pixel value. Aggregate every one of the items together to get a "score" for the overlay. the various techniques to match the images are as follows: Figure 1.5 what is it? Figure 1.4 Template matching is a technique which matches the sample template with the source image . THANK YOU one of 6 template matching techniques in cv::matchTemplate(OpenCV function) is used .* For every area of T over I, metric is put away in the resultant matrix (R). Every area (x,y) in R contains the match metric . Utilizing the cv::minMaxLoc function in the OpenCV to find the most astounding worth (or lower, depending of the sort of matching method) in the R matrix . Confine the area with higher matching likelihood ,Draw a black color rectangle around the region relating to the most elevated match.    Figure 1.9 SUM OF SQUARED DIFFERENCES Square differences normed Cross correlation Coefficient normed Detected point This method will match the squared difference between the template and the source image. so a exact match will be '0' and poor matches will be large.
