• (p. 3) In Figure 1.1, the labels for the three sets of plots should be j=1, j=2, and j=3 rather than j=0, j=1, and j=2
• (p. 10) The J₀ should have a minus sign before it in the left-hand limit of the interval (five lines under the displayed equation).
• (p. 11) In the sentence beginning "This detail function ..." about 2/3 of the way down the page, the first J₀ in the superscript of f should be J₀-1.
• (p. 11) In equation (1.8), the limits of the integral should be k2^-j and (k+1)2^-j.
• (p. 13) In the first equation, the second summation should be over k rather than over l.
• (p. 13) In the third displayed equation, there should be "(x)" just before the equals sign.
• (p. 13) In the last equation, neither norm should be squared.
• (p. 14) Just under the first displayed equation (for V_j), the second sentence should read "Each subspace V_j consists of functions that are piecewise constant over intervals of exactly half the length of those for V_j-1 (and twice the length of those for V_j+1)."
• (p. 16) In the displayed equation in the middle of the page, the argument of the function on the right hand side should be 2^jx -k.
• (p. 20) The coefficient values for j=1, k=-4 and for j=1, k=3 should both be 0.9805. Here's the corrected table.
• (p. 21) The coefficient value for j=0, k=-2 should be -0.9207 and that for j=0, k=1 should be 0.9207. Here's the corrected table.
• (p. 51) The c_J,k in the text after (3.3) should have a hat (^) on it.
• (p. 51) In the expression for the histogram just over halfway down the page, the j' should just be j.
• (p. 63) The first line in the last full paragraph on the page should begin "The algorithms given in (4.8) and (4.9) share . . ."
• (pp. 64-65) The equations (4.12), (4.13), and (4.14) should have parentheses around the entire summands to make it read more clearly.
• (p. 119) The first sentence in Section 7.1 should refer to Section 3.2.
• (p. 122) In the third line of the derivation of the expected value of the wavelet coefficient, there should be a (1/n) term before the summation sign.
• (p. 122) In the first line of the variance computation, there should be parentheses around the n i the wavelet coefficient's superscript.
• (p. 122) In the second-to-last line of the second set of equations, the wavelet function should be squared.
• (p. 131) In the last equation on the page, the right-hand side should be multiplied by n.
• (p. 131) The third line from the bottom should have ellipses: k = 0, . . ., 2^J-1 -1.
• (p. 148) In the first displayed formula on the page, there should be a (1/d) on the right hand side.
• (p. 159) In equation (8.8), the superscript on the second threshold value in the equation should be n/2 rather than n.
• (p. 162) In the first displayed formula on the page, the d should be a w.
• (p. 175) In the last sentence on the page, j_i = i should read instead j_i = i-1. Also, the limits on the union in Equation 9.4 should run from i=0 to infinity. For further reading on this topic, see "Entropy-based Algorithms for Best Basis Selection" by Coifman and Wickerhauser, IEEE Transactions on Information Theory, Vol. 38, Number 2, pp. 713-718 (1992).
• (p. 178) In Figure 9.6, the G's and the H's should be switched. To be consistent, the G's and H's should be switched in Figure 9.7 as well.
